A color-blind female has children with a male that has normal vision. Which of the following is the most likely outcome for their potential offspring?
A |
All female children will be color blind. |
|
B |
All of their children will have normal vision. |
|
C |
All male children will be color blind. |
|
D |
They will only have female children. |
Answer:
c. All male children will be color blind.
Explanation:
Xc = Coloblind X-chromosome
XC= Normal chromosome
XcXc (female) x (male)XCY ---Parents

XCXc (normal but carrier daughters) |
XcY (color-blind sons) |
All female children are normal.
All male children are with color-blind
A color-blind female has children with a male that has normal vision. Which of the following...
1.) If a male who is color-blind has children with a female who is a carrier for color-blindness, what is the possible phenotypic ratio of their offspring? Use numbers in each blank out of 4 possible offspring: ________ girls with color vision : ________girls without color vision : _________boys with color vision : ________boys without color vision. 2.) If two dihybrid pea plants, PpSs and Ppss (P=purple flowers, p=white; S=starchy seeds, s=sweet), what are the genotypic and phenotypic ratios? Use...
A male achondroplastic dwarf with normal vision marries a color-blind woman of normal height. The man's father was six feet tall, and both the woman's parents were of average height. Acondroplastic dwarfism is autosomal dominant, and red-green color blindness is X-linked recessive. How many of their female children might be expected to be color blind and average to tall height (i.e., not an anchondroplastic dwarf)? all none half one of four three of four
A woman with the recessive, X-linked disorder hemophilia has children with a male who is color-blind, also a recessive X-linked disorder. What is the probability that their children will have hemophilia and have normal vision? a. 0 b. 1/4 c. 1/2 d. 3/4 e. 1
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...
Muffy, a color blind female with blood type A (heterozygous) is married to Biff, who is also color blind and is homozygous for type B blood. Muffy has been having an affair with their gardener, Raoul, who is heterozygous for type B blood and has normal vision. Recall that color blindness is a sex linked recessive condition. Please help Biff’s attorney determine the father of each of the children for the divorce proceedings:a) Female, type A blood, normal visionb) Male,...
Question 14 3 pts A normal vision male X'Y marries a carrier female for red-green color blindness XX. What is the chance they will have a color blind son? 25% 100% 75% 0% 50%
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?...
A male with normal vision marries a woman who is color-blind. She gives birth to a daughter who is also color-blind. The husband claims the child is not his. The wife claims the child is his. Can you support the argument of either parent? If yes, which one? Why?
11. A boy, whose parents and grandparents had normal vision, is color-blind. What are the genotypes for his mother and his maternal grandparents? Use XB for the dominant normal condition and Xb for the recessive, color-blind phenotype 12. In humans, sickle cell anemia is a disease caused by a mutation of a single locus gene which codes for an important blood protein. The allele for the normal protein (S) is dominant to that for the one causing sickle cell anemia....
Bob has Klinefelter's syndrome (XXY) has normal color vision. His mother was color-blind due to a homozygous recessive mutation on the X chromosome (XbXb), but his father had normal color vision (XBY). Which parent underwent non- disjunction? Explain your answer.
