Question

In a monohybrid cross, if the gene for tall (T) plants was incompletely dominant over the gene for short (t) plants, what would be the predicted result of crossing an intermediate (Tt) plant with a tall (TT) plant? (Hint: You may want to complete a Punnett square.)

Answer 1

Answer:

           T            t

T       TT           Tt

T        TT           Tt

The punnet square shows that there will be a 50% chance that the offsrpings will have tall height and there is a 50% chance that the offsprings will have intermediate height.

Incomplete dominance can be described as a phenomenon in which the dominant trait is not completely dominant over a recessive trait. As a result, the organisms shows both the traits of the dominant and the recessive allele.
