Answer:

The correct answer would be meiosis.

In diploid organisms, meiosis is the process that results in the formation of four haploid daughter cells from single diploid parent cell. Each of the daughter cell contains half the number of chromosomes present in parent cell.

It results in the formation of haploid gametes (sperm in males and eggs in females) which is essential in the process of sexual reproduction.

The fusion of gametes results in the formation of diploid zygote that is, maintains the diploid nature of the organism.

Hence, in absence of meiotic division the chromosomal number would keep on doubling after each generation.

In addition, crossing over (exchange of genetic material between non-sister chromatids) also takes in the prophase-I of meiosis I. It increases the genetic variation within organisms of the species. It may add survival adaptations to the population.

The process of sexual reproduction involves two parents contributing one gamete each. Gametes are produced by the process meiosis in which exchange of chromosomes happen causing genetic variation. Good luck!

il63 [147K]

Answer:

One difference between monotremes and other types of mammals is that monotremes secrete milk through pores on the surface of the mother's abdomen.

Explanation:

Monotremes are three different types of mammals. They are calsified by structural differences in their jaws, reproductive tract, brains, digestive tract, and some other body parts compared to the more common mammalian types. Monotremes secrete milk through pores on the surface of the mother's abdomen, they actually <em>lactate from their mammary glands via openings in their skin.</em>
