Recombination is a central biological process with implications for many areas in the life
sciences. Yet we are only beginning to appreciate variation in the recombination rate along …

With more than 70,000 living species, vertebrates have a huge impact on the field of biology
and research, including karyotype evolution. One prominent aspect of many vertebrate …

Sex differences in overall recombination rates are well known, but little theoretical or
empirical attention has been given to how and why sexes differ in their recombination …

An unusual supernumerary chromosome has been reported for two related avian species,
the zebra and Bengalese finches. This large, germline-restricted chromosome (GRC) is …

Meiotic recombination through chromosomal crossing-over is a fundamental feature of sex
and an important driver of genomic diversity. It ensures proper disjunction, allows increased …

The chicken continues to hold its position as a leading model organism within many areas of
research, as well as being a major source of protein for human consumption. The First …

In many instances, there are large sex differences in mutation rates, recombination rates,
selection, rates of gene flow, and genetic drift. Mutation rates are often higher in males, a …

Rapidly accumulating genome sequence information in birds, which show several unique
genomic features, provides novel insights into evolutionary genomics. The avian karyotype …

Background Genetic linkage maps are essential tools when searching for quantitative trait
loci (QTL). To maximize genome coverage and provide an evenly spaced marker …

Germline-restricted chromosomes (GRCs) are accessory chromosomes that occur only in
germ cells. They are eliminated from somatic cells through programmed DNA elimination …
