Question

How chromosomes are maintained in the human gamete?

Answer 1

The number of chromosomes in each generation are maintained due to meiosis. The meiosis is a kind of reductive division. When gametes are formed by meiosis, the number of chromosomes are halved. Hence each gamete will have only one pair of chromosome.

Later the haploid gamete will fuse with the complementary haploid gamete and form Diploid Zygote(2n). Hence the number of chromosomes are maintained.
