Question

ten frogs live in a pond in your backyard. five are homozygous for an allele that results in dark skin, and five are homozygous for an allele that results in lighter skin. a drought occurs, killing three frogs with light skin alleles. did the frog population evolve? click or tap a choice to answer the question. yes no

Explanation:

Evolution occurs when allele frequencies change. Initially, dark - allele frogs: 5, light - allele frogs: 5 (total 10). After drought, light - allele frogs: \(5 - 3=2\), dark - allele frogs: 5 (total 7). The frequency of light - skin allele decreased, so allele frequencies changed.

Answer:

yes
