The fraction of offspring that the Punnett square predict will be tall is ¾ (option C).

<h3>What is the punnet square?</h3>

The punnet square is a graphical representation used to determine the probability of an offspring expressing a particular genotype.

The punnet square is used to predict the percentage or proportion of offsprings of a cross that possess a specific genotype.

According to this question, a punnet square shows a cross between two tall pea plants. The allele for tall height (T) is said to be dominant while the allele for short height (t) is recessive.

If two heterozygous genotype crosses i.e. Tt × Tt, the percentage of offsprings that will be tall is 75% or ¾.

Therefore, the fraction of offspring that the Punnett square predict will be tall is ¾.
