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 two intermediate (Tt) parent plants? (Hint: You may want to complete a Punnett square.)
1) 25 percent tall, 50 percent intermediate, 25 percent short
2)50 percent tall, 25 percent intermediate, 25 percent short
3)100 percent intermediate
4)25 percent tall, 75 percent intermediate

Answer 1

Based on the question, TT will be tall, tt will be short, and Tt will be somewhere in between (intermediate) since T is incompletely dominant.

The cross we're talking about is Tt x Tt. If you draw out the Punnett square, you'll see pretty quickly that you'll have 1 TT, 2 Tt, and 1 tt offspring.

Or, in other words, 25% tall, 50% intermediate, and 25% short. This first option is your answer!

Thank you so much guys :)))
