do not list any duplicates.

a. Aa c. AaBB
b. AaBb d. AaBbCc
Solution:
a) As the genotype carries only one type of allele the possible gametes will be of only two.
The F1 generation of the above genotypes will be
Genotypes Aa
F1 generation A x a
So the possible gametes are A and a
b) In the second one there are two kinds of genotypes with both are heterozygous so there may be
chance of 4 kinds of gametes
A a
B AB aB
b Ab ab

The four different possible gametes are AB,aB,Ab,ab
C) In the third case the genotypes bear a homozygous and as well as heterozygous the number of
possible gametes are only two as there should not be any duplicates
A a
B AB aB
B AB aB
The possible gametes for the following is only AB, aB
d) A three different traits with heterozygous allele and the gamete formation are also being more.
The possible gametes for the genotype AaBbCc are ABC, ABc, AbC, aBC, abC, aBc, Abc, abc.
