Ann Massoud Preston Biology 22 February 15, 2008 Weekly Study Question #3 You are an evolutionary biologist studying three different populations of a certain species of poisonous frogs, they come in three different phenotypes: light green with spots, dark green with no spots, and medium green with very few spots. The dark green with no spots (G) has incomplete dominance over the light green with spots (g). You know that the heterozygotes are the medium green with few spots (Gg). You go and observe the frogs in their natural habitat for a while, count them, and then end up with this data:

Unformatted text preview: Number of frogs with each Phenotype: Dark Green with no Spots Medium Green with few spots Light green with spots Population 1: 3,250 5,220 1,530 Population 2: 495 360 145 Population 3: 52 32 16 What are the frequencies of the Dark green with no spots and Light green alleles with spots of each population? Population 1: (GG): (3,250 + 2,610)/10,000 x 100 = 58.6% (gg): (1,530 + 2,610)/10,000 x 100 = 41.4% Population 2: (GG): (495 + 180)/1,000 x 100 = 67.5% (gg): (145 + 180)/1000 x 100 = 32.5% Population 3: (GG): (52 + 16)/100 x 100 = 68% (gg): (16 +16)/100 x 100 = 32%...
