Question

On pea plants, the location of flower growth is an inheritable trait. Axial flower position (A) is dominant over the recessive trait of terminal flower position (a). 

In the parental generation, a homozygous dominant axial flower position pea plant is crossed with a terminal flower position pea plant. 

1.  Draw a digital Punnett square of the F1 offspring producing the F2 offspring. 

2.  In the F2 generation, what is the probability one plant will have a terminal flower position? 

3.  In the F2 generation, what is the probability two plants will have axial flower positions? Show all work digitally.
