Genome landscape and genetic architecture of recombination in domestic goats (Capra hircus).

ABSTRACT:

Background

Recombination is a fundamental biological process, both in participating to the creation of viable gametes and as a driver of genetic diversity. Characterising recombination is therefore of strong interest in breeding populations. In this study, we used ~ 50 K genotyped data and pedigree from two French populations (Alpine and Saanen) of domestic goats (Capra hircus) to build sex-specific recombination maps, and to explore the genetic basis of two recombination phenotypes: genome-wide recombination rate (GRR) and intra-chromosomal shuffling.

Results

Sex-specific recombination maps showed higher recombination in males than females for both breeds (Alpine autosomal map size = 35.1 M in males and 30.5 M in females; Saanen map size = 34.0 M in males and 29.0 M in fema
