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.
