C I know this is hard but it’s easy
Offspring with a 3:1 ratio suggest that both parent that both parent that give rise to this offspring were both heterozygous. Heterozygous individual is someone who has two different allele at a locus whereby by one gene is dominant over the other gene. example of heterozygous parent is a parent Aa pair of alleles. In this pair gene A is dominant over gene a
According to the research, the correct option is A, population genetics is the study of how allele frequencies in a population change over time.
<h3>What is population genetics?</h3>
It studies the origin, amount and distribution of genetic variability present in populations.
It explains the variation between individuals, as well as the dynamics of alleles and genotypes within and between populations.
Therefore, we can conclude that according to the research, the correct option is A, population genetics is the study of how allele frequencies in a population change over time.
