B)the differences between humans and mice are mainly the introns.
C)they have very little in common.
D)the genomes are very similar,with most of the genes unique to mice linked to size and shape.
E)the genomes are very similar,with most of the genes unique to mice linked to smell and reproduction.

Question

Quizplus · Accepted Answer

Comparisons of human and mouse genomes have shown that they are very similar overall. A significant portion of the genes that are unique to mice are indeed linked to smell (due to a large number of olfactory receptor genes) and reproduction, reflecting differences in these species' ecological niches and reproductive strategies.
