The evolution of molecular genetic pathways and networks

In their analysis, they suggested that proteins of similar ages (which they refer to as isotemporal categories) have a greater tendency to interact with each other than if they were in different age groups. Moreover, it appears that the networks tend to grow via addition of modules or groups of inte ...

This probably occurs because fully sex-linked beneficial mutations substitute at different rates from autosomal ones, especially when fitnes ...

Quantitative genetics and breeding theory

Group coancestry based measures are (like inbreeding) relative to some reference population. For forest tree br ...

... Genes which are carried on the X chromosome are said to be sex-linked. It is easy to spot recessive defects in genes located on the X chromosome because the genes are expressed more frequently in males. This occurs because males normally have only one X chromosome. Males therefore have all genes loc ...
