Pea plants can have two alleles for height: T (tall stem) and t

(short stem). Two plants with genotype Tt and tt are crossed,

and the 300 resulting seeds are planted. How many of the

offspring are predicted to be short? Write your answer as a

whole number with no decimals.

150

Explanation:

Given that T is dominant and t is recessive, a punnett square would show a 50% chance (1:1 ratio) for each kind of offspring (tall or short). Therefore, it can be predicted that 150 seeds will produce short pea plants.
