| A | B |
|---|
| coat color in rabbits | controlled by multiple alleles |
| trait expressed by many phenotypes | controlled by many genes on many chromosomes (polygenic) |
| linked genes | genes found on same chromosome |
| red cow x white bull ----> roan | co-dominant trait |
| red flowers x white flowers --->pink flowers | incomplete dominance |
| phenotype that will survive exposure to malaria | Carrier for sickle cell disease |
| gene maps are based on | frequency of crossing over between linked genes |
| the farther apart two genes are located on a chromosome | the less likely the genes will be inherited together |
| Another genotype for A blood besides AA | AO |
| genotype of Black lab dog | EeBb |
| genotype of yellow lab dog | eeBb |
| coat color in lab dogs controlled by | two genes and 4 alleles |
| offspring of cross between blood type A x blood type B | A, B, AB, O |
| X-linked trait | expressed more in males |
| # of alleles controlling fur color in rabbits | four |
| hemophilia | blood clots won't form |
| Studied genetics of fruit flies to earn Nobel prize | Thomas Morgan |
| co-dominant | alleles are equally dominant, both traits are expressed |
| incomplete dominance | neither allele is dominant, a blending of phenotypes |
| multiple alleles | trait controlled by 3 or more alleles for one gene |
