WebSexual reproduction is the union of male and female gametes to form a fertilized egg, or zygote. The resulting offspring inherit one half of their traits from each parent. Consequently they are not genetically identical to either parent or siblings, except in the case of identical twins. As hypothesized by Mendel, adults are diploid, signified ... WebGametes are produced by the cell division which is called meiosis. Gamete formation takes place in these sequences of steps, replicated DNA in a parent cell is distributed among four cells. Meiosis produces gametes that are considered as the haploid cells. Human sex cells contain 23 chromosomes.
