Question

The table below provides information about a population in which natural selection acts on a single-genetic trait.
Frequency of Alleles
Year
Frequency of Allele B
Frequency of Allele b
1910
0.81
0.19
1930
0.49
0.51
1950
0.25
0.75
1970
0.10
0.90
What can be inferred from the information in the table?
Diversity in the gene pool increased over time.
Allele B was dominant in 1910 but became the recessive allele over time.
The frequency of both alleles in this population decreased from 1910 to 1970.
From 1910 to 1970 the likelihood of surviving was higher for individuals with Allele b.
