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.
A female cat should be allowed to attain her adult size before breeding. If bred early, she will put her energy into feeding the unborn/newborn kittens instead of finishing her growth. She will be 18-24 months old before she is ready for breeding. A male should be 18 months of age prior to being allowed to breed. This allows time to determine if he is healthy and suitable for breeding.
