Correct Answer: in gametes

Solution : The correct option is in gametes.

Genes are not found in pairs in gametes. The specialised reproductive cells known as gametes, which include sperm, and egg cells, are haploid, meaning they have half as many chromosomes as the organism's diploid somatic (body) cells. The procedure that halves chromosomal numbers is called meiosis. Following fertilisation, the gametes fuse, and the developing zygote becomes diploid, containing one allele from each parent. The genetic diversity of a child is increased by this mix of alleles from both parents.
