A "TT" (tall) plant is crossed with at "tt" (short) plant. What percentage of the offspring will be tall?

100%

Explanation:

My biology teacher taught me the FOIL method. F=first, O=outside, I=inside, and L=last.

TT x tt

The first letter of each parent together would be Tt, T=tall so the plant would be tall, 25%

The outside letter of each parent together would be Tt, T= tall so the plant would be tall, 25%

The inside letters of each parent together would also be Tt, T=tall so the plant would be tall, 25%

The last letter of each parent together would also be Tt, T=tall so the plant would be tall, 25%

Each outcome has a T, and that is dominant so therefore, the plants will always be tall. You could also think about it as a letter has to be passed down to each child and the first plant only has capitals to pass and the second only has lowercase to pass down.

100% of the offspring will be tall.

answer; i believe the correct answer is ( proteins );
