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 short (tt) plant? (Hint: You may want to complete a Punnett square)

25 percent tall, 50 percent intermediate, 25 percent short
75 percent intermediate, 25 percent short
100 percent intermediate
50 percent intermediate, 50 percent short

Answer 1

Answer:

The correct answer is 50 percent intermediate, 50 percent short .

Gametes formed by intermediate (Tt) parent plants would be T and t.

Recessive parent plant would produce only one type of gamete which is t.

Hence, only two types of offspring would produce after their cross: Intermediate (Tt) and short (tt) and that too in equal proportion i.e. 50% intermediate and 50% short.

The punnet square is shown in the figure attached for reference.
