Department of Animal breeding and Genetics, Justus Liebig University Giessen, Germany. INTRODUCTION Genetic markers provide information about allelic variation at a given locus. The increasing availability of molecular markers in farm animals allows the detailed analyses and evaluation of genetic diversity and also, the detection of genes influencing economically important traits. The majority ...

totally, 3200 and 320 young worker bees were investigated morphologically and molecularly respectively. the four important honey bee microsatellite loci, a24, a28, a29, a113, indicated a considerable level of genetic diversity among the nation’s northwest honey bee populations and, considering average number of alleles per locus (3.25-5.75) and, average expected heterozygosity (0.445-0.701) hig...

The growth hormone receptor (GHR) is a member of cytokine/hematopoietin family that mediates the biological actions of growth hormone (GH) on target tissues. Therefore, the purpose of this study was to examine the association of TG-repeat polymorphisms in the 5’-flanking region of bovine GHR gene with milk production traits and somatic cell score (SCS) in Holstein cattle of Iran. The part of 5’...

The impact of biotechnology on mango enhancement, particularly through genetic engineering and molecular markers, has been significant. Biotechnology revolutionized the field agriculture, offering innovative tools techniques for improving crop traits. In case mangoes, involves manipulation organism's DNA to introduce or modify specific genes, targeting traits such as disease resistance, fruit q...

 DNA markers are integrally connected to the success of molecular breeding and are fundamentally required by breeders to be able to, a. identify new gene sources in the available biodiversity, b. select parents in order to increase heterosis, c. decrease the number of backcross generations for gene introgression breeding programs, and d. carry out marker-assisted selection (MAS). The present re...
