This work provided the genetic data which is very helpful for determining the genetic diversity of cattle population, breed identification, animal forensic and paternity cases and making effective breeding policies and conservational activities in future. This work is very helpful about breed characterization of two cattle breeds (Red Sindhi and Tharparker) and developing understanding about genetic architecture of cattle breeds as present study conclude that six SNPs were present in both breeds, four private to Red Sindhi and 22 were private to Tharparkar.
Genetic diversity remains the fundamental step for plant improvement in era of genomics. Understanding how diversity is structured is not only a prerequisite for systematic sampling of the germplasm but also helps in designing suitable conservation strategies. Syzygium cumini (Black Berry) is a large evergreen multipurpose tree of family Myrtaceae. The tree which is native to India thrives easily in tropical climate and is found in many parts of Asia and Eastern Africa. S. cumini is widely used world wide in treatment of diabetes. This work demonstrated how genetic diversity is structured in Syzygium populations. This book shows how dominant markers (RAPD and ISSR) could be used for tree species in population genetic analysis. Apart from genetic analysis, phytochemical variations have been studied together as a tool for authentication of germplasm and biodiversity evaluation.

Extensive genetic diversity in natural parasite populations is a major obstacle for the development of an effective vaccine against the human malaria parasite, since antigenic diversity limits the efficacy of acquired protective immunity to malaria. Genetic diversity is one of the prominent features of Plasmodium falciparum infections. To the best of our knowledge, This is the first effort of elucidation and genetic correlation has not been investigated before on genetic diversity of P.falciparum field isolates from Jharkhand, India and as such it bridges an important gap in the understanding of the molecular characteristics of the parasite population in South East Asia, especially Jharkhand, India, an understudied and tribal dominant region with perennial malaria.Our data provided the link between the genetically acquired immunity, infection and diversity through complex interplay of transmission cascade in population exposed to falciparum malaria.
DNA barcode assisted Molecular Taxonomy for species identification aided us to employee this technique in discrimination of fishes from Narmada river basin, one of the longest river of India. During our study we found high genetic diversity between individuals isolated by barriers (dams/waterfalls) this facilities us to study, how barriers contribute to the fragmentation of the genetic structure in the fish communities. This study serves as first report of its kind for river system on the Indian subcontinent.
Genetic diversity plays a very important role in survival and adaptability of a species because when a species’s environment changes, slight gene variations are necessary to produce changes in the organism's anatomy that enables it to adapt and survive. This book, therefore, provides an idea on molecular markers such as RAPD, ISSR and SSR technologies to detect genetic diversity of the selected medicinal plants. The advantages of molecular markers for the generation of genetic linkage maps and molecular analysis in plants have been established extensively within a short span of their inception as an efficient marker system. Their widespread use has served as a considerable genomic resource for plant breeder's providing them with an array of suitable tools for a range of target applications such as analysis of genetic diversity. Knowledge of population genetic diversity is one of the prerequisites for development of plant species conservation strategies. In the case of wild species that represent genetic resources for cultivated plants, an understanding of their genetic diversity is essential as they are the source of genetic material that are used to improve elite varieties.
Rohu is the most popular food fish in Bangladesh. It is a first growing fish in rivers and even in ponds and other closed water bodies.Now-a-days, the natural habitats are being destroyed due to anthropological effects such as urbanization, overfishing and other developmental activities. Alongside, the hatchery originated rohu fish are often being hybridized with the catla and mrigal to increase production. The ignorant hatchery operators produce seedlings by uncontrolled breeding through interspecific and intergeneric hybridization that cannot ensure expected growth rather loss their genetic quality. As a result, the purity of rohu stocks is being gradually lost. It is important to reveal that the chromosomal studies and karyotype analysis of wild and hatchery rohu populations to identify pure and hybrid rohu, to prevent loss of genetic variation i.e. DNA erosion and protect them from endangered situation.
This study confirmed the high genetic diversity among date palms in Sudan which was reported in previous studies. The use of morphological characterization, molecular analysis and interviewing of farmers, assisted in the successful fulfillment of the set of objectives to collect, document and analyze data pertaining to the present status of local date palm genetic resources in the Northern region of Sudan (River Nile and Northern States) with regard to cultivars, production and threats. The results of this study will contribute to the formulation of a national strategy for the conservation and sustainable use of the date palm genetic resources in Sudan. Further studies including chloroplast DNA to identify the origin of the seedling cultivars (Jaw and males) are warranted.
The study was conducted to assess the genetic diversity in crop plants for optimization of sampling and breeding strategies. Genetically diverse gene pool is vitally important in varietal development. Molecular markers were utilized to explore the genetic diversity among native and exotic germplasm. In the proposed study Random Amplified Polymorphic DNA (RAPD) markers were used to assess the genetic diversity among 20 selected linseed varieties/lines.
Chickens are agriculturally important animals and valuable model organism. Many inbred lines of chickens are well characterized for disease resistance and production traits. In general, biodiversity can be described at several levels from phenotypic observations to molecular data. Recent advances in molecular technology have opened up new horizons in assessment of genetic variability at the DNA level. Microsatellites are a group of DNA markers which are widely used to study genetic biodiversity in chicken. In present book, at first, we have reviewed application of different DNA markers in studying biodiversity in chicken; then different microsatellite markers have been used to study among and within genetic diversity of six Indian chicken populations. This book can be especially useful for students and researchers who are willing to know microsatellite analysis in chicken more in details.

Genetic diversity was assessed using 15 morphological characters. Based on multivariate (D2) analysis, 60 mango genotypes were grouped into 8 clusters. Three enzymes viz., gulutamate oxaloacetate transminase (GOT), malate dehydrogenase (MDH) and peroxidase (PER) were used to investigate genetic diversity of 60 mango genotypes at protein level. Eight zymotypes with GOT, 10 with MDH and 7 with PER were formed by 22, 39, 12 bands, respectively at different Rf values. Compared with three studied DNA extraction protocols of mango such as SDS, CTAB and water saturated ether (WSE) method with NaCl, it was found that WSE method with NaCl had highest value of average percentage (85.44%) in DNA content of the mango genotypes. Study of RAPD for 60 mango genotypes was done to detect genetic diversity at DNA level. Of 40 primers, 11 decamer primers amplified 104 bands. The mean genetic diversity among all the accessions was 0.323 and Shannon's information index was 0.489 across all loci. Induction of mutation on 8 selected genotypes derived from morph-molecular diversity study was performed by applying three doses of radiation such as 20 Gy, 30 Gy and 40 Gy.
The RAPD markers are an efficient tool for assessing the genetic diversity and are less expensive then molecular techniques like AFLP, RFLPs etc. therefore more convenient for use in research.This book basically covers the basic methodology used for assessing the genetic diversity like DNA isolation,quantitative and qualitative Estimation of DNA,RAPD-PCR,Agarose gel electrophoresis, Gel documentation,and use of Bioinformatics tool for data analysis. Rapid molecular testing techniques for the verification of elite genotypes/cultivars identity assume importance in the face of demands for exacting quality in international trade, need for ensuring homogeneity in planting stocks and protection of intellectual property rights on indigenous biodiversity of O. sanctum present in central India. The present study has shown the usefulness of RAPD markers for diversity analysis of O sanctum genotypes as well as cultivars obtained from different localities, particularly identification of the specific bands may be considered important in the identification and for conservation of species and may lead to planning of a better management of conservation program in the country.
