Mitosis is the process of separating chromosomes in its cell nucleus into two identical sets in two nuclei within eukaryotic cells. As for when it takes place, I believe it stâ¦arts after the G2(second gap) stage of Interphase ends.
A rabbit may normally start breeding at the age of 6 months for the small to medium size breeds and 8 to 9 months for the heavy breeds. The gestation period (time between breeding and kindling) is 31 days. After the doe has kindled, I normally re-breed her at 6 weeks and wean the litter at 5-7 weeks.
Deer mice begin breeding at only about six weeks of age, their gestation time is 24 days, and each female can produce up to eleven litters each year with about 2-9 young in each litter. The babies are weaned at 4 weeks of age and are ready to breed and increase the deer mouse population in another two weeks. Deer mice are carriers of the Hantavirus.
