Ans: 50 percent.
Explanation: The red-green color perception defect is due to a mutation on the X-chromosome which is responsible for red-green color blindness. X-linked red-color blindness is a recessive trait. Females have a 100% chance of being carriers of this gene. Females heterozygous for this trait have normal vision. Males inherit their single X-chromosome from their mothers (here mother is color blind) and become red green color blind. Hence there is almost certainly a 50% chance that any one of your sons will be affected by red-green colorblindness.

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.
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...
In humans, colorblindness is X-linked and recessive. A male with normal vision and a colorblind female mate. If their child is a girl, what is the chance that she is colorblind? 100% 25% 0% 50%
Red-green colorblindness is an X-linked, recessive trait. Suppose a group of 100 female and 100 male astronauts is sent to colonize a planet. 20 of the males are colorblind. 10 of the females are colorblind, and 30 are carriers. If this population were to establish a randomly mating colony in regards to this trait, what would you predict the frequency of colorblind males to be in the population over time if it were to immediately achieve and remain in Hardy-Weinberg...
Red-green color blindness is X-linked recessive. A woman with normal color vision has a father who is colorblind. The woman has a child with a man with normal color vision. What is the probability their child is a boy and is colorblind? A. 1/8 B. 1/4 C. 1/2 D. 3/4 E. 0
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...
Colorblindness is a sex-linked X-linked recessive trait. A normal woman marries a color-blind man. They have a color-blind daughter. What are the genotypes of all three people?
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...
Suppose color blindness is a X linked trait in humans. It is also recessive. A phenotypically normal woman has a father with color blindness. This woman marries a man with normal vision. What is the chance of their children being color blind? What is the chance of their daughters being color blind?
NAME: 6. Red-green color deficiency is an X-linked recessive trait. A woman with normal color vision has a father who is color-deficient. The woman has a child with a man with normal color vision. Which phenotype is NOT expected as a possibility for that child? a) a color-deficient male b) a color deficient female c) a male with normal color vision d) a female with normal color vision 7. Which of the individuals in the human pedigree shown below allow...
