| The ___produced by each parent are shown along the sides of a punnett square. | gametes |
| genotype Aa | heterozygous |
| Mendel's law of segregation | factors (alleles) that control traits seperate and only 1 factor from each pair are passed to the offspring. |
| The passing on of traits from parents to offspring | heredity |
| Cells containing two alleles for each trait | diploid |
| The gamete that contains genes contributed only by the mother | an egg |
| Genes located on homologous chromosomes have alternate forms of a trait. The alternate forms are | alleles |
| Linked genes | Never seperate |
| The closer genes are located on a chromosome | Increases likelyhood for linked together |
| Recessive traits | Only when organism has two recessive alleles for a trait. |
| polygenic trait | more than one gene controlls for a trait |
| hair color/skin color | polygenic trait |
| multiple alleles | more than two variations for a trait, however, only two alleles will be used |
| codominance | Offspring exhibit both characteristics of parents |
| Incomplete dominance | offspring are a blend between two parents. |
