Dihybrid Cross: Dimples and broad eyebrows In humans, the allele for dimples (D) is dominant to the allele for no dimples (d). At another gene locus, the allele for broad eyebrows (B) is dominant to the allele for slender eyebrows (b). These two allele pairs assort independently. A man who is heterozygous for both traits marries a woman who has no dimples and who is heterozygous at the gene locus controlling eyebrow width. Complete the sentences about this dihybrid cross with the correct terms. 50% dd, 50% Bb 50% Dd, 50% Bb 1/2 DDBB 25% DB, 25% Db, 25% dB, 25% db 50% dB and 50% db 1/4 3/8 9/16 50% d, 25%B, 25% b ddBb 1/8 db 25% D, 25% B, 25% d, 25% dB DdBb The genotype of the man is The genotype of the woman is The genotype of the gametes produced by the man is The genotype of the gametes produced by.the woman is The probability that their first child will have dimples is The probability that their first child will have dimples and slender eyebrows is
