9. An offspring of many generations that has the same form of a trait
10. Passing of traits from parents to offspring a person's child or children.

2. An offspring of crosses that has two different alleles for a trait
3. Different forms of a gene
5. A chart that shows all the possible combinations of alleles that can result from a genetic cross
