Question

Some traits are determined by more than two alleles. Human skin color is determined by three different genes, resulting in sixty four possible skin tones. If a father with skin tone aabbcc has children with a mother whose genotype is AABBCC, what would be the genotype of their children? A) AABBCC B) AaBbCc C) aabbcc D) aaAAbbBBccCC

Answer 1

The answer would be b.)AaBbCcThey because will receive one recessive allele from their father and one dominant allele from their mother at each gene locus.

Answer 2

Answer:

(B). AaBbCc.

Explanation:

In humans, each somatic or body cell has two sets of chromosomes, as one set comes from mother and one sets comes from father. Each gene shows two or more forms, known as alleles.

If the genotype of mother is AABBCC and the genotype of father is aabbcc, genotype of their children would be AaBbCc as each parent will transfer to the offspring as shown below:

Parents:               AABBCC                aabbcc

                              (mother)                     (father)

                                   ↓                                ↓

Gametes:                ABC             x            abc

                                                     ↓

Genotype of offspring:            AaBbCc

Thus, the correct answer is option (B).
