Genetic drift tends to occur in populations that
Are small
Are formed from new species
Are very large
Have unchanging allele frequencies

Genetic drift may occur when a small group of individuals colonize a new habitat. True or false. Two populations that have overlapping ranges can remain reproductively isolated through behavioral isolation or temporal isolation from each other.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
