I need help answering these 4 questions, but mostly question number 3. Please look at the image so you have access to the questions. Thanks for your help in advance <3

Question 1: D

To solve for Punnett squares, take the letter from the corresponding row and the letter from the corresponding column and write both in the corresponding box.

For instance, there is a capital T in the left column and a capital T in the top row. In the top - left box, "TT" would be written.

You can do this for the rest of the boxes to receive "Tt" for the top - right box, "Tt" for the bottom - left box, and "tt" for the bottom - right box.

The correct choice is D.

Question 2: E

This question uses the same Punnett square as the last.

The last one had combinations of TT, Tt, Tt, and tt - so 25% of the offspring have the genotype tt, meaning short.

Question 3: L

The genotype of an offspring is its gene combination - so the TT, Tt, and tt I was describing earlier. The phenotype is its appearance - in this case, purple or white.

Box 2 has a purple flower with a genotype of Bb, so the correct choice is L.

Question 4: S and T

Heterozygous genotypes can also be called "mixed" genotypes. They have both genes. In this case, that means Bb (instead of the homozygous genotypes of bb and BB).

Box 2 and 3 have the genotype of Bb, so the correct choices are S and T.

where is the scientific experiment?
