(N/A) During sexual reproduction,the process of meiosis (reduction division) occurs during gamete formation. This process reduces the chromosome number to half in both male and female gametes. When these two haploid gametes fuse during the process of fertilization,the diploid number of chromosomes,which is identical to that of the parents,is restored in the zygote and subsequently in the offspring.
