Why is meiosis a key step in sexual reproduction? Select all that apply. creates gametes with two sets of chromosomes creates the necessary male and female gametes prevents male and female gametes from combining creates gametes with one set of chromosomes

creates the necessary male and female gametes

creates gametes with one set of chromosomes

Explanation:

Meiosis is a type of cell division employed by sexually-reproducing organisms. It produces four genetically different daughter cells that have their chromosome number reduced by half i.e. from diploid (2n) to haploid (n). Meiosis is the process whereby organisms produce their necessary gametes needed for sexual reproduction.

Male organism produces haploid male gametes(n) while female organisms produce haploid female gametes (n). These gametes contain one set of chromosome (haploid) because they have to unite in a process called FERTILIZATION. When they do, they form a diloid zygote (2n), which has the same number of chromosomes as each parent cell. That is n+n= 2n.
