Male Trinidadian guppies use bright red patches of color to attract mates. Your colleague has recently sequenced 400 individual guppies at the opsin gene that controls sensitivity to red wavelengths in light. He has found a new variant of this gene that increases sensitivity to red in his samples. Unfortunately, a computer malfunction has scrambled his data and he no longer knows which alleles come from heterozygotes or homozygotes. Based on his recods, 80 of the 800 alleles sequenced are the new variant. If this gene is in H-W equilibrium in this population, how many individuals from his sample of 400 should be homozygous for the new allele?
