Heritability and repeatability of paternal haplotype recombination rate in beef cattle autosomes

Abstract

<p>Recombination and de novo mutations generate genetic diversity in a population, which is the key element for evolution and selective breeding. The variation in recombination rate across the genome and the recombination hotspots can be estimated by haplotype analysis. However, the crossing-over rate is not uniform across different individuals. In this research, we estimated the recombination rate across the autosomal chromosomes of 4 Australian beef cattle breeds. Further, we estimated variance components, heritability and repeatability of recombination rate within each breed.</p>
