FromTheMoon [43]

Dominant phenotype will be expressed on homozygous dominant(BB) and heterozygous(Bb) type. Using hardy-Weinberg equilibrium, the percentage of individual with brown eye would be:
homozygous dominant= BB= 70%*70%= 49%
heterozygous = 2Bb= 2* 70%*30%= 42%

Total brown eyes= homozygous dominant+ heterozygous
Total brown eyes= 49%+42%= 91%
