How much genotypic variation do you find in the randomly picked parents of your crosses? How much in the offspring?
| Possible Genotype | Parents | Offspring |
| YY | 3 | 4 |
| Yy | 3 | 10 |
| yy | 4 | 6 |
| Total | 10 | 20 |
b. How much phenotypic variation do you find in the parents of your crosses? How much in the offspring?
2. (10 points)
a. What is the ratio of phenotypes (yellow kernel color: blue kernel color) in the 20 offspring of your five crosses?
b. If you were to run this experiment 1000 times, rather than just 5 times, what would you expect the ratio of phenotypes to be in the offspring?
c. Is the ratio of observed phenotypes the same as the ratio of predicted phenotypes in the offspring? Why or why not?
3. Organisms heterozygous for a recessive trait are often called carriers of that trait. Explain what this means. (10 points)’
