Accepted Answer

Part 7 produces the ovum, which is known as the ovaries. The primary role of ovaries is to have an ovum. Hence option (iv) 7 is correct. The fertilisation process takes place in part 5, which is called a fallopian tube or oviduct. Hence option (ii) 5 is correct. The embryo implantation takes place in part 4, which is known as the uterus. The shape of the uterus is inverted and pear-shaped. Hence option (iv) part 4 is correct. The block is created surgically in part 5, called fallopian tubes, tofertilizationilisation. Hence option (ii) part 5 is correct. The nucleus can be transplanted from an early-stage embryo to the unfertilized egg, which is enucleated. This process is known as nuclear transplantation, which induces the development of the host egg according to the instructions of the newly inserted nucleus, in which the formation of an organism with the same genetic material as the donor cell.   Hence option (iv) Formation of the viable embryo in the recipient eggs, is correct.
