Question

red-green colorblindeness occurs more commonly in men than it does in women. using this information, which chromosome do you suppose the gene for red-green colorblindness resides on, and is the trait dominant or recessive?

Answer 1

Answer:

Usually the Y chromosome. It is recessive because if one Y chromosone is mutated with red-green colorblindness and the X is not, the child will have colorblindness. But, if one X chromosome has the mutation and the other X does not, they will cancel out, meaning the child will not have colorblindness.
