Ans. Fertilization and Development in Rabbit
Rabbits can breed throughout the year but male rabbits are commonly sterile during the summer months. Male rabbit deposits its sperms in the vagina (birth canal) of female.Sperms swim through cervix and uterus to fallopian tubes where they fertilize the egg cells, released from ovary. After fertilization, zygote is carried to uterus. By this time, the zygote has started dividing and is now called embryo.The embry is implanted in uterus walls. A connection, called placenta,is established between embryo and uterus wall. Embryo develops into new offspring (rabbit kit) in 30-32 days, after which it is
born.
