A gene locus has two alleles A, a. If the frequency of dominant allele A is 0.4, then what will be the frequency of homozygous dominant, heterozygous and homozygous recessive individuals in the population?

1. 0.16 (AA); 0.36 (Aa); 0.48 (aa)

2. 0.36 (AA); 0.48 (Aa); 0.16 (aa)

3. 0.16 (AA); 0.24 (Aa); 0.36 (aa)

4. 0.16 (AA); 0.48 (Aa); 0.36 (aa)
