Accepted Answer

A)  All the offspring were tall. 
B)  Half the offspring were tall, the other half were short. 
C)  All the offspring were short. 
D)  The offspring were intermediate in height relative to the two parent plants. 
E)  About 90 percent were tall, but the rest were short.

Question 2

What are the typical Mendelian phenotypic and genotypic ratios in the F2 generation for a cross of purebred tall and short plants? Why are these ratios typical?

Accepted Answer

In classical Mendelian genetics, when cr

C)  All 
D)  1/4 
E)  2/3
