For the experimental research, Dr. Ian Wilmut used the nucleus of the udder cell from a six-year-old Finn Dorset white sheep and preserved the diploid nucleus (2n). He took an ovum from the ovary of another sheep. The haploid ovum was removed. The diploid nucleus of the udder cell was injected into the cytoplasm of the enucleated ovum. Then the diploid nucleus ovum was implanted into the uterus of the surrogate mother sheep. The diploid ovum developed into a young one, named “Dolly”.

ii) Define the terms haploid and diploid.
