Question Asked by … WebIt is the process by which the number of chromosomes is reduced by half to form sex cells (sperm and eggs). During meiosis the chromosome pairs separates and are distributed to two different cells. The resulting sex cells have only half as many chromosome as the other cell in the organism.

WebAs half of the genetic make-up of the offspring is from one organism and half from another, it is genetically different from its parents. In other words, it shows variation. 1; 2; 3;
There are a wide range of reproductive strategies employed by different species. Some animals, such as the human and northern gannet, do not reach sexual maturity for many years after birth and even then produce few offspring. Others reproduce quickly; but, under normal circumstances, most offspring do not survive to adulthood. For example, a rabbit (mature after 8 months) can produce 10–30 offspring per year, and a fruit fly (mature after 10–14 days) can produce up to 90…
