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.
Answers. Best Answer: Your female is old enough to start breeding. Females are fertile up to ages 8-10. Males are fertile to breed until 12-14 years of age. Cockatiels need to be at least one year old before you start breeding them.Age isn't the only consideration in breeding. The cockatiels must be in good health, eating a well-balanced diet, and not molting. The pair must be compatible or they won't breed.They don't have to be the same ages to breed.ockatiels need to be at least one year old before you start breeding them.
