| ressive | a gene that can be controlled by a dominant form when both alleles of the gene in a pair are recessive. |
| gene | one of the many parts of a DNA molecule that contains genetic instructions for a certain trait. |
| allele | two genes interact to produce characteristics. Two copies of genes are alleles. The two alleles together make a gene. |
| punnett square | a chart used to show all the possible different genotypes of offspring from a particular male and female parent. |
| environmental factor | Anything that changes the environment and influences living organisms. |
| genetic factor | Genetic variations that can have large or small effects on the likelihood of developing a particular disease. |
| adaptation | A characteristic that helps an organism survive in its environment or reproduce. This may be passed to the organism’s offspring through its genes. |
| homozygous | A characteristic that helps an organism survive in its environment or reproduce. This may be passed to the organism’s offspring through its genes. |
