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.
Both sexes can start breeding at 6 weeks of age and continue until they are about 12 months old. A females first litter often produces a smaller number of babies, as do those from female over 9 months of age. Breeding mice is an easy business as long as you remember one simple rule.That is ONLY ONE MALE TO A CAGE. have found that 2 to 4 females to one male in a standard mouse cage works fine. How many young they produce depends on their environment and breed of mice. Most pet shop mice produce small litters of about 3 to 12 babies. There are some laboratory breeds of mice that produce litters of up to 25 babies every 28 days.
