Q.
Number of gametes produced by a homozygous and a
heterozygous individuals o f genotype $AA $ and $Aa$,
respectively are
Principles of Inheritance and Variation
Solution:
The formula to calculate the number of gametes from a given genotype is $2^{n}$.
Where, $n=$ number of heterozygosity in the given genotype.
Thus, number/types of gametes produced by a homozygous individual of genotype $AA$ is $2^{(0)}=1$
and by heterozygous individual of genotype Aa is $2^{(1)}=2$.
