Description : Genes are not found in pairs - (1) in body cells (2) in ovary after fertilization (3) in gametes (4) in zygotes
Last Answer : (3) in gametes Explanation: Genes are a part of the chromosome and are found in pairs in somatic cells. One member of the gene pair segregates into a gamete, thus each gamete only carries one member of the gene pair. Gametes unite at random and irrespective of the other gene pairs involved.
