Red-green color blindness is a sex-linked trait, with the normal vision phenotype being dominant (C) and the color blind (c) phenotype being recessive. If you are male and your father is color blind, what is the chance (expressed as a percentage) that you will inherit his trait for color blindness? What if your mother is a carrier for color blindness (but your father is not color blind), what is the chance of you being color blind? Make sure...

Red-green color blindness is an X-linked recessive trait. Heterozygous females have normal color vision but are carriers of the allele for red-green color blindness. Based on the information presented in the pedigree, select all of the females from the list below that are known carriers of red-green color blindness.

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...

SEX-LINKAGE Red-Green color-blindness is sex-linked X-linked recessive trait. A normal sighted woman whose father is color- blind marries a color-blind man. they have 20 children. Of those 20, 6 are normal sighted females, 5 are color-blind females, 4 are normal sighted males and 5 are color-blind males. 7. What are the genotypes of the parents and all the children? 8. Theoretically, what would be the genotypic and phenotypic ratios of the offspring?

*why do sex-linked traits (X- linked traits) such as red-green colorblindness (which is recessive) display a different pattern of genetic inheritance from autosomal recessive traits? and does it make a difference whether the sex-linked trait is dominant rather than recessive? how? *what are the chances a boy will be colorblind if his mothers father was 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...

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...

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.
