Because the red eyes are recessive to black eyes, the parents could be heterozygous. Recessive alleles only show if two recessive alleles are combined. Thus the offsprings phenotypes of the gene would be C. Rr and rr

raketka [301]

Answer:

Explanation:

From the question, the total population = 171 i.e (80+71+21)

Genetic frequency therefore; BB = 71/171 = 0.42

Bb = 80/171 = 0.47

bb = 20/171 = 0.12

Allele frequency therefore;

Allele B = 0.42+(0.50×0.47) = 0.66

Allele b = (0.50×0.47)+0.12 = 0.36

Note all values were rounded up to two significant figures
