Answer 1

Meiosis begins with one haploid cell and ends with four diploid cells. Fertilization is the exchange of genetic material between homologous chromosomes.

Chromosome segregation occurs at two separate stages during meiosis called anaphase I and anaphase II (see meiosis diagram). In a diploid cell there are two sets of homologous chromosomes of different parental origin
