What are the resulting phenotype for each cross? Are there any blue kernels?
1. (10 points)
a. Set up and complete Punnett squares for each of the following crosses: (remember Y = yellow and y = blue)
· Y Y and Y y
| Parent 1 | |||
| Y | Y | ||
| Parent 2 | Y | YY | YY |
| y | Yy | yy |
· Y Y and y y
| Parent 1 | |||
| Y | Y | ||
| Parent 2 | Y | Yy | Yy |
| y | Yy | Yy |
b. What are the resulting phenotypes for each cross? Are there any blue kernels?
| Y Y and Y y | Y Y and y y |
|
The resulting phenotypes is that all the offsprings are yellow because all the offspring have at least one Y (yellow, dominant) allele
|
All the offsprings are yellow |
There are no blue kernels in either cross and all are yellow because the genotypes of all the kernels have at least one dominant (Y) gene which codes for yellow color.
