3. An organism's sex cell, which contains half the total number of chromosomes.
4. The division of the genetic information in reproductive cells, so that they have only half the normal number of
chromosomes.
5. A section of a chromosome made up of DNA, the fundamental unit of heredity.
6. A chain of amino acids; examples include hormones, enzymes, and antibodies.
7. To receive a trait from an ancestor.
