Answer 1

C

Step-by-step explanation:

The correct answer is C because any with the dominant purple, B, will have a phenotype of Blue.

Answer 2

1) 75% purple flowered and 25% white flowered. If you complete the punnett square, you'll see the combinations are PP, Pp, Pp, and pp. The capital P is dominant (purple), so you know that 3/4 combinations will be purple flowers.

2) 50%. There is a 50% chance Grace will have Huntington's disease because since the disease is dominant, it is capital letter H. When you make a punnett square, you'll see the combinations are Hh, Hh, hh, and hh. There is a 50% chance Grace will have the Hh combination.

3) Protein. Protein is the only bio-molecule out of the 4 options, and the diagram shows a protein being made.

4) Transcription. Transcription is when the genetic message from DNA is transcripted onto mRNA.
