All of the following events occur during normal meiosis except _______. A. two haploid gametes fuse to form a diploid cell B. on
lesya692 [45]

Answer:

A. two haploid gametes fuse to form a diploid cell

Explanation:

Meiosis is a type of cell division. When a parent cell with "2n" chromosomes enters the process of meiosis, four daughter cells each with "n" chromosomes are formed. This occurs since homologous chromosomes separate from each other during anaphase-I. However, meiosis does not include the fusion of two haploid cells. The fusion of two haploid cells mainly occurs during the process of fertilization during which a haploid male gamete and a haploid female gamete fuse to form a diploid zygote.
