Morgan Color
What was the significance of finding Morgan Thomas?
Thomas Hunt Morgan, working with fruit flies, fruit flies found males may have the character of white-eyed mutant, even if they had one "white" allele. What was the significance of this discovery? a. it led to the discovery of aneuploidy b. it led to the discovery of polypliidy c. It led to the conclusion that only males Y chromosomes have d. it was found that crossing over occurs between chromosomes X and Y e. This enabled it to award the stroke of the eye color on chromosome X.
Aneuploidy is the condition of having an abnormal number of chromosomes, whereas polyploidy is the condition of having more than two complete sets of chromosomes, or has to do with the discovery of Morgan. I think they knew that only men have Y chromosomes (as he calls its conclusion) and is not crossing between X and Y chromosomes, so the answer would be (e). Males are hemizygous for the X chromosome, if this chromosome X one has a sex-linked trait on him, he will be expressed, whereas in females, two X chromosomes with the recessive gene are necessary for milking expressed in the phenotype.
