a- 30 b-10 c-29 d-28 cycles
2- the open reading frame of the mRNA consists then of: (for the given above)
a-29 sense codons b-30 sense codons c-31 sense codons d-29 codons

Hello Sir,

I have a test regarding some questions as below.
It is very, very important for me, I hope I get some answer from a expert.

Question 1: " Explain the main type of interaction between alleles of different genes"
Question 2: "Explain the main type of interaction between alleles of one and the same gene"

Thanks in advance.

Best regards

In garden peas a pure line that is tall with purple flowers is crossed to another pure line that is short with white flowers. The F1s are all short and white. You cross the F1s with each other and get 900 short white, 315 short purple, 307 tall white, and 99 tall purple. You allow 90 of the short purple F2 plants to self-fertilize and then select a single seed from each one. What phenotypes would you expect to see in the plants reared from these seeds and in what numbers? Why?
