| Why were the offspring tall when Mendel crossed homozygous tall plants with Homozygous short plants | The allele for tall plants is dominant |
| what type of inheritance occurs when you cross a white hen with a black rooster and get an offspring with both black and white feathers? | co-dominance |
| Two plants with the genotypes TT and Tt | would have the same phenotype |
| What is the probability that a human sperm cell will carry an X chromosome? | 50% |
| Why is colorblindness is more common in males than females | The allele for colorblindness is recessive and located on the X chromosome |
| Which sex chromosomes represents a female | XX |
| How many total chromosomes are shown in a normal human karyotype? | 46 |
| If a cross between a black guinea pig (BB) and a white guinea (bb) pig result in all black offspring, the allele for black color is_______ | dominate |
| For each gene an individual typically has ____ allleles. | 2 |
| Skin color in Humans is an example of ______ | multiple alleles |
| Human blood type is an example of _____________ | Co-dominance |
| How did Mendel's discoveries about hereditary factors come about? | analysis of the offspring of pea plant crosses |
| The best way to determine the coat color phenotype of an animal would be to ____ | Observe the animal |
| heterozygous | a pair of genes where one is dominant and one is recessive — they're different |
| homozygous | a pair of matching alleles, which are the two genes that control a particular trait |
