AP BIOLOGY

Detailed explanation-1: -To form a fetus, an egg from the mother and sperm from the father come together. The egg and sperm each have one half of a set of chromosomes. The egg and sperm together give the baby the full set of chromosomes. So, half the baby’s DNA comes from the mother and half comes from the father.

Detailed explanation-2: -This is known as “heredity” or “inherited genes."

Detailed explanation-3: -Genetic information is passed from generation to generation through inherited units of chemical information (in most cases, genes). Organisms produce other similar organisms through sexual reproduction, which allows the line of genetic material to be maintained and generations to be linked.

Detailed explanation-4: -You got all your genes from your parents. For each pair of their chromosomes, you get one chromosome from your mother and one from your father. When the egg and sperm cells come together, they create the full set of 46 chromosomes or 23 pairs.
