Question

The table here shows information about four different populations of a flowering plant species. The relative population sizes, level of genetic variation, and presence of selective pressures are indicated in the table. Analyze the data and evaluate in which population is natural selection most likely to cause a shift in the alleles and phenotypes?

Responses
A II
B IIII
C IIIIII
D IV

Answer 1

Population C, with the highest level of genetic variation and the presence of selective pressures, is most likely to experience a shift in the alleles and phenotypes due to natural selection. The other populations have lower levels of genetic variation and/or no selective pressures, which would make them less likely to experience changes in allele frequency due to natural selection.
