| In rainbow trout, you are studying scale color and patterning.
You have identified two genes: R = rainbow scale color, where loss of function confers a "gray-scale" color phenotype. S = stripe pattern, where loss of function confers a spotty pattern phenotype. You cross a rainbow horizontal striped fish to a gray spotty fish with the following strange result: (Female) RRSS x (male) rrss -> RrSs with phenotype gray and striped. Which parent was the recessive gray allele inherited from, and what can be said about which parent is imprinting which gene? |

The answer of the question is given below if you have any doubt then feel free to ask in the comment box and guys don't forget to trigger the thumbs up.
Answer: Female; Male imprints R
If you have any problem with the answer then don't forget to comment me.
Thanks.

What genes (or kind of genes) will you focus on in your investigative research? Provide 2-3 reasons for your choice of these gene/s. Starting with the bone sample itself, what methods will you use to get DNA that you can sequence? Which “ingredients” in your lab reactions will determine which gene or genes are copied? How is it that these ingredients are able to target a specific gene? What method will you use to see if your efforts to copy...
