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?

3. Colour-blindness is a X-linked, recessive trait. If a normal-sighted woman, whose father was colour-blind, marries a colour-blind man, what is the probability that they will have a son who is colour-blind? (use the letter "B") 4. A man and woman, both of normal vision, have: 1) a colour-blind son (#1) who has a daughter of normal vision 2) a daughter (#1) of normal vision who has one colour-blind son and one normal vision son 3) another daughter (W2) of...
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?
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?
A woman is phenotypically normal but her father had the sex-linked recessive condition of red-green color blindness. If she marries a man with normal vision, what is the probability that their two children will both have normal vision? 4/9 1/16 3/4 9/16 3/8
Color blindness is a sex-linked trait. A woman who is normal but a carrier for color blindness married a normal man. Describe their offspring in percentages, ratio, and gender and color blindness.
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...
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...
A woman with red-green color-blindness has a mother with normal vision. Knowing that color-blindness is a sex-linked recessive gene, can you determine what her father's phenotype is? (yes or no) If so, what is it?The woman marries a man with normal vision. What is the probability they will have sons who are red-green color-blind? What is the probability they will have daughters who are red-green color-blind?
SEX-LINKED TRAITS 8. Create a Punnett square to determine the offspring that would result from a cross between a woman with normal vision, who carries the allele for color-blindness, and a man who has normal vision. Note: color-blindness is an X-linked recessive tret What are the genotypes of the parent? List all possible genotypes of the offspring. male, normal male, color-blind female, normal vision female, carrier 50% Co hat percentage of their sons would be color-blind? What percentage of their...
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
