Q 63 . How many types of phenotypic and genotypic categories respectively are produced by genotype aa Bb cc DD Ee ff :-

(1) 4, 8                                      (2) 9, 4                                  (3) 16, 9                                  (4) 4, 9

Dear student,
Answer is 1) 4,8
Since there are two heterozygote (Bb and Ee) therefore four gamete will be formed by 2ⁿ formula where n = number of heterozygotes.
Gamete formed are:- aBcDEf, aBcDef, abcDEf, abcDef
Crossing the gamete produces sixteen offspring in which four types of phenotypes are found and eight types of genotypes are found.
