Question

HELP PLEASE!! I just want to know how to put this in a punnett square can someone please show me? Thank you! :)

Answer 1

In fruit flies, the gene for red eyes (R) is dominant and the gene for sepia eyes (r) is recessive. If a red-eyed heterozygous fly (Rr) mates with a sepia-eyed homozygous fly (rr), what are the possible genotypes of their offspring? (Hint: You many want to complete a Punnett square.)

Answer 2

Can you please explain how you did this?

Answer 3

??

Answer 4

First you draw the little box thing like I did. Then, you take one of the letter pairs (rr or Rr) and put it on top of the box and take the other letter pair and put it along the side. The you go and match up the letters. For example, look at the first little box inside the big one. Take the letter above it and the letter beside it and put them into that square. So you will always be taking the letters from the outside of the square and pairing them up in new combinations in each little box inside the big box. Hope this helps. I am a bit confusing sometimes. Let me know.
