Is cloning by sexual reproduction

Answer 1

No. Sexual reproduction involves a fusion of the nuclear contents of one gamete (say, a sperm), with the nuclear contents of another gamete (say, an egg). The resulting cell has two alleles, or versions of a gene, for every gene in the (nuclear) genome. This cell (a zygote) thus has a full diploid nuclear genome, having derived half of its genes from its father and half from its mother.

During cloning (at least during somatic cell nuclear transfer, which is one type of cloning method), a full diploid nucleus from a somatic cell is transferred to an egg cell that has had its nucleus entirely removed. In this way, all of the nuclear genes come from one individual- whoever the nucleus of the somatic cell's owner was.

So, to reword, during sexual reproduction, half the genome comes from the mom and half from the dad, but during cloning, the whole genome comes from one individual, but gets put into an egg that has been emptied (or, enucleated).
