Red-green colorblindness is a sex-linked trait. Normal color vision results from the dominant allele (A) while red-green colorblindness results from the recessive allele (a). In the cross X(A)Y x X(A)X(a): Select one: O a. All males should be red-green colorblind, all females normal o b. males have 50% chance of colorblind, all females will have normal O c. males have 50% chance of colorblind, all females will be colorblind O d. all males have normal vision, 50% of females will...

3. In humans Red-Green colorblindness is due to an X-linked recessive allele. A woman was diagnosed with colorblindness in her right eye, but nommal vision in her left eye. It is known that her father was colorblind and that her mother had normal vision. Explain how the phenomena of dosage compensation could explain this woman's condition.

Select one answer. Colorblindness is any abnormality of the color vision system that causes a person to see colors differently than most people, or to have difficulty distinguishing among certain colors (www.visionrx.com). 10 points Colorblindness is gender-based, while the majority of sufferers being males. Roughly 8% of white males have some form of colorblindness, while the incidence among white females is only 1%. A random sample of 20 white males and 40 white females was chosen. Let X be the...

Red-green color blindness is inherited as an X-linked recessive (Xc). If a color-blind man marries a woman who is heterozygous for normal vision, what would be the expected phenotypes of their children with reference to this character? In your answer, specify in your phenotype descriptions the gender of the children. (For example, don’t just say 75% of the children would be colorblind – you would instead say 100 % of the daughters would be colorblind and 50% of the sons...
