uppose a hew predator moves into same environment as a bird species. The predator can more easily see birds that are red (the dominant phenotype), and can less easily see birds that are brown (the recessive phenotype). Before the new predator arrived, the frequency of the recessive allele was 0.5 and the frequency of the dominant allele was 0.5. a. What was the frequency of the heterozygous (Bb) genotype before the new predator arrived? b. What was the frequency of the homozygous dominant genotype (BB) before the new predator arrived? C. After the new predator arrived, the frequency of the recessive allele increased to 0.7. What is the new frequency of the dominant allele? d. What is the new frequency of the heterozygous (Bb) genotype after the new predator arrived?

Question
Suppose a new predator moves into same environment as a bird species. The predator can more easily see birds that are red (the dominant phenotype), and can less easily see birds that are brown (the recessive phenotype). Before the new predator arrived, the frequency of the recessive allele was 0.5 and the frequency of the dominant allele was 0.5. a. What was the frequency of the heterozygous (Bb) genotype before the new predator arrived? b. What was the frequency of the homozygous dominant genotype (BB) before the new predator arrived? C. After the new predator arrived, the frequency of the recessive allele increased to 0.7. What is the new frequency of the dominant allele? d. What is the new frequency of the heterozygous (Bb) genotype after the new predator arrived?
