Question

why diploid nucleus is used in cloning ?for 2 marks......

Answer 1

First I must define the terms to be used in this discussion:

Diploid (of a nucleus)- Containing two complete sets of chromosomes.

Haploid (of a nucleus)- Containing one set of unpaired chromosomes.

It is generally the case that the diploid nucleus contains a set of chromosomes from each parent. A new nucleus will obtain its chromosomes during fertilisation, that over-romanticised stage when the gametes unite to form the zygote.

In simpler words: A haploid swimmer meets a haploid egg and their nuclei fuse to form a new nucleus that is diploid.

This describes sexual reproduction and is a complex process that introduces more variation into the population: A Good Thing.

In cloning, we’re not interested in sexual reproduction or in the production of variation. No, in cloning we want an exact copy of what we’re cloning. In order to do that, we need a cell that has the full set of chromosomes required to grow an organism, so we take any one of the somatic (body) cells of the organism we’re cloning and all of these cells are diploid.
