You compare the genomes of two related species. You find that genes that regulate developmental processes (the ones that shape how the body forms) exhibit a lot of non-synonymous substitutions, while genes involved in basic cell function exhibit more synonymous substitutions. What does this indicate?

Reagan Coleman · Answer 1

It means that the developmental regulation genes are being affected by drift, while the basic cell function genes have a lower rate of mutation.

Jair Chambers · Answer 2

The developmental regulation genes are being affected by drift, while the basic cell function genes have a lower mutation rate.

A chunk of loci on a chromosome that are in strong linkage disequilibrium suggests that one of the loci in the middle of that was probably under recent strong selection.

Explanation:

The more closer the alleles are located on a chromosome higher is the frequency of getting inherited together.

Distance between alleles on chromosome, genetic drift, mutation are some of the factors affecting linkage disequilibrium
