Respuesta :
The answer is 25 percent tall, 50 percent intermediate, 25 percent short.
So, we know:
TT - tall plant
Tt - intermediate plant
tt - short plant
After crossing two intermediate plant Tt, each can give either T allele or t allele to the offspring (take a look at the uploaded image with Punnett square):
Parents: Tt x Tt
Offspring: TT Tt Tt tt
So:
1 of 4 offspring will be tall (TT): 1/4 = 0.25 = 25%
2 of 4 offspring will be intermediate (Tt): 2/4 = 1/2 = 0.5 = 50%
1 of 4 offspring will be short (tt): 1/4 = 0.25 = 25%
So, we know:
TT - tall plant
Tt - intermediate plant
tt - short plant
