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” .
i) Why did Wilmut select the udder cell?
ii) Define the terms haploid and diploid

i)
Wilmot used the udder cell for the cloning of the sheep because the scientists had found a way of reprogramming the udder cell.
They were able to keep them alive without making them grow.
ii)
Haploid is defined as the state in which the cell has the half the number of chromosomes.
After meiosis, the number of chromosomes in cell is half.
This state is known as haploid .
Gametes are haploid cells.
Diploid cells contain two sets of chromosomes.
When two haploid cells(gametes) fuse together, they form diploid cell.
