Question 6 • Biology_B_IC_Alt

creates new alleles from DNAbrings new alleles from other populationsrandomly selects allelesfavors certain alleles A zebra migrates to join a different herd of zebras.

Answer
A
creates new alleles from DNA
B
brings new alleles from other populations
C
randomly selects alleles
D
favors certain alleles

Explanation

When the zebra joins a different herd, it moves between populations and may introduce its alleles to that herd through breeding. This is gene flow, which brings alleles from other populations. It does not create new alleles or favor particular alleles.
