Q. How many types of gametes can be produced by a diploid organism who is heterozygous for 4 loci?

NTA AbhyasNTA Abhyas 2020

Solution:

Gene locus is a fixed position of a gene on a chromosome. Heterozygotes contain contrasting alleles for an allelic pair. Therefore, if a diploid organism is heterozygous at four loci, it will have four different contrasting characters present at four different loci.
Hence, the types of gametes produced will be $=$ $ \, 2^{n}$ where $n$ is number of heterozygous loci. Thus, gametes produced by a diploid organism could be $2^{4}=16$ .
