Answer #1

The gametes refer to the sex cells that conduct the genetic substance from both the parents and transfer it to the offspring. Both the females and males generate gametes. A male gamete and a female gamete combine to produce a zygote that gives rise to an offspring. The gametes exhibited by males are called sperms, and the gametes exhibited by females are called egg cells or ova.


Explanation of Solution :
The gametes are generated via the process of cell division called meiosis in which a parent cell, that is, diploid goes through replication of DNA, succeeded by two cell divisions in order to generate haploid cells. A human being carries a diploid chromosome set and a total of 46 chromosomes. However, the gametes exhibit only half of the chromosome set, that is, a haploid set of chromosomes.
