Detailed explanation-1: -The embryo develops within a specialised part of the oviduct called uterus or womb, the embryo establishing an intimate contact with the uterine wall and the young are born alive so that the eutherian mammals are viviparous.
Detailed explanation-2: -Uterus. The female rabbit has a bicornuate duplex uterus. This has two separate uterine horns and no uterine body. Each horn has its own cervix, and the two cervices open into a single vagina.
Detailed explanation-3: -Implantation of rabbit embryos takes place around 7 days following artificial insemination (Orsini, 1962). The length of the gestation varies slightly by breed, averaging 30–31 days depending on litter size.
Detailed explanation-4: -Ovulation and preimplantation embryo development. Female rabbits have a uterus duplex, i.e. two separated functional uteri and cervices, with a vagina simplex. The uterus duplex allows the transfer of two embryo groups to the same recipient female.
