Answer #1

Male with normal vision: XY

Colorblind female: XcXc

Progeny: XXc,XXc,XcY,XcY

So the girl child will be carrier of this disease, but not affected by this disease. So the answer is 0%.

    D. 25% orme condition. The male is XX and the female is XY. But X-linked genes have the same effects in mugwumps as in humans. A recessive X-linked allele "n" produces red-green color blindness. The dominant allele "N" produces normal color vision. If a female mugwump with normal color vision mates with a male mugwump, phenotypically normal for color vision but whose mother was color blind, what is the probability that a son from that mating will be color blind?...

    10. Red green colorblindness is an X-linked recessive disease. That means that it is carried on the X chromosome, so men have just one copy of the gene while women have two. In women, both copies must be the recessive disease allele in order to show the disease phenotype, but because men only have one allele, just one recessive allele causes the disease phenotype. Matt and Kate both have normal vision, but Kate's father is colorblind. Use X for the...
