Kauppi, L. In the simulations with allowed recombination between X and Y chromosomes and the recombination value equal to that between X and X, we received the characteristic distribution of fraction of defective genes Fig. Coronavirus: Find the latest articles and preprints.
Expansion of the pseudo-autosomal region and ongoing recombination suppression in the Silene latifolia sex chromosomes. The species were selected based on previous reports of chromosomal morphology and availability of live material. Sinauer, Sunderland, Ensembl
They determine the sex of an individual. Insights into hominid evolution from the gorilla genome sequence. Autosomes are homologous chromosomes i. The initial recombination rate stayed unchanged for only very short time and then rapidly decreased to 0 after 17, MC steps Fig.
The divergence between chromosome region and genes was corrected for multiple substitutions using the formula of Jukes and Cantor The elimination of deleterious mutations on the X increases the fitness of females at the expense of males. Schneider, J.
They are different in males and females by their size, form, and behavior.
Publisher's note: Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. There are also other reasons why the recombination did not stop completely in nature. However, results changed significantly when the recombination between the X and Y chromosomes was forbidden.
Therefore, this assumption can model a high probability of zygotic death, which is actually observed in nature 84
