Atall pea plant (tt) is crossbred with a short pea plant (tt). the following punnett square shows the separated alleles for two pea plants. which of the following shows the correct match of the box numbers and the genotype of the offspring? 1 = tt; 2 = tt; 3 = tt; 4 = tt 1 = tt; 2 = tt; 3 = tt; 4 = tt 1 = tt; 2 = tt; 3 = tt; 4 = tt 1 = tt; 2 = tt; 3 = tt; 4 = tt

The answer would be option A. 1 = Tt; 2 = tt; 3 = Tt; 4 = tt

The graphed version would look like this:

   T     t

t    Tt   tt

t    Tt   tt

Explanation:

Since one parent has Tt and the other is tt. This means that there should be about 25% of that "T" trait within the offspring. This is because there are three out of four of the traits (parents traits all-together) are recessive or "t". So that dominant trait is 25% of the traits of both parents.

So the offspring must display, 25% dominant trait. So, if the offspring is Tt, tt, Tt, and tt. What I did to make it easier, is I literally combined all the 'T' and 't' together. So there are two of the 'T' and six of 't'. If you do the math 2/8 is indeed, 25% of the data. So this answer would be correct.

(However if you are wondering why it is not option C. Yes the numbers are correct, but the order is not. If you look at the boxes, the boxes are numbered. Using the mini graph I made above, you use that to determine which goes with what number. The graph (numbered) looks like this:)

  T    t

t  1    2

t  3   4

I REALLY hope this helps!! Have a great day and don't forget to smile! :)))
