Solution
The correct option is B AaBbccDDEeFf
The individual which is heterozygous for 4 genes will produce 16 different types of gametes. Hence, the correct answer is AaBbCcDDEeFf.
The first option has only four pairs of genes and one pair is homozygous recessive. This combination will not give 16 gametes.
The second option (correct answer), although has two pairs in homozygous condition, remaining four pairs will give rise to 16 gametes.
The third option has 6 gene pairs but 3 are in homozygous condition. hence this combination will give less than 16 gametes.
The fourth option has 5 gene pairs in heterozygous conditions and it will give 64 combinations.
