| what is dominant allele | mask any other form present |
| what is recessive allele | the form of a gene thast is masked |
| what is homozygous | an individual that has two of the same alleles for a gene |
| what is heterozygous | an individual that has two differetn alleles for a gene |
| what is test cross | crossing an unknown individual with a recessive individual t determine whether tthe unknown individual is heterozygous or homozygous |
| what is incomplete dominance | neither allele mask the other but instead you see an intermediate in the heterozygous |
| what is codominant alleles | when neither allele mask the other but instead you see both alleles appear |
| what is multiple alleles | more than two alleles influence the same gene |
| what is polygenic traits | traits such as hair color that are controlled by more thatn one gene |
| what is karyotypes | diagrams that arrange chromosomes from largest to smallest in order to detect diseases caused by nondisjunction |
| what is pedigrees | a chart, similar to a family tree that traces a particular trait or disease |
