Molecular Markers for Fertility in Farm Animals
A genetic marker is a gene or DNA sequence with known localization on a chromosome. It can be de-scribed as a variation that can be measured or detected by a suitable method, and can be used subsequently to detect the presence of a specific genotype. Such variations occurring at chromosomal or DNA level can serve as genetic markers. The progress in development of molecular markers suggests thei...
متن کاملThe Pattern of Linkage Disequilibrium in Livestock Genome
Linkage disequilibrium (LD) is bases of genomic selection, genomic marker imputation, marker assisted selection (MAS), quantitative trait loci (QTL) mapping, parentage testing and whole genome association studies. The Particular alleles at closed loci have a tendency to be co-inherited. In linked loci this pattern leads to association between alleles in population which is known as LD. Two metr...
متن کاملApplication of Molecular Genetic Technologies in Livestock Production: Potentials for Developing Countries
Application of Molecular Genetics in livestock production has been reviewed indicating that why molecular genetics is important in the presence of conventional livestock improvement programs. Molecular genetic technologies like marker assisted selection, PCR, DNA sequencing, tran genesis and cloning have been discussed. The paper includes the applications of Molecular biotechnologies in animal ...
متن کاملMarker assisted selection for the improvement of Sarjoo-52 for drought tolerance by introgression of MQTL1.1 from the source Nagina–22
Literatures have reported that a lot of drought related genes were cloned and individual gene showed positive effects under controlled stress experiments, but were not much effective in the field. Although, the progresses by conventional breeding approaches were achievable as some drought varieties have been released to the farmers in the recent years but this is not adequate to cope up with th...
متن کاملDeveloping heterotic groups for hybrid breeding in crop plants with emphasizing on forage crops
Exploitation of heterosis in hybrid breeding and development of synthetic cultivars is an essential procedure in plant breeding programs. The main goal of hybrid breeding programs is to select desirable parental genotypes to maximize the expression of heterosis. However, since development of high yielding hybrids and synthetic cultivars are costly and time-consuming, the accurate prediction of ...
