Answer 1

ANSWER

An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome.

All the DNA in the cell makes up the human genome. There are about 20,000 important genes located on one of the 23 chromosome pairs found in the nucleus or on long strands of DNA located in the mitochondria

In genetics, a locus (plural loci) is a specific, fixed position on a chromosome where a particular gene or genetic marker is located.
