उत्तर
On chromosomes, genes are regarded as functional segments. The structural and operational unit of heredity is the gene. If genes are missing from the chromosomes, the offspring will not resemble the parent. Since the gene is the genetic unit that transmits the traits from one parent to the next, the absence of genes will prevent the baby from resembling its parents. It resides in a nucleus and is composed of DNA.
