# Tall pea plants are dominant over short pea plants. If there are 200 short plants in the F2 generation from a cross that followed Menders methods, about how many plants from will be tall in that generation?

I got $600$ plants with the Tall phenotype.

#### Explanation:

If F2 contains $200$ short plants (phenotype: tt)
then based on my (possibly incorrect understanding)
there should be approximately:
$\textcolor{w h i t e}{\text{XX}} 200$ with genotype TT and
$\textcolor{w h i t e}{\text{XX}} 400$ with genotype Tt
for a total of $600$ tall plants.
