1. Which parent(mother or father) determines if a son is colour-blind ?
Sol-The genes received from mother determines if a child is colour-blind or not
2. Genotype of a homozygous recessive individual (Use letter "A") ?
Sol- Homozygous Recessive Genes have to recessive alleles i.e "aa"
3.Which Chromosome are the sex chromosomes ?
Sol-The XY Chromosomes are the sex determining chromosomes
QUESTION 1 Which parent (mother or father) determines if a son is color blind? QUESTION 2...
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.
Suppose a woman with a color blind father and a mother with no history of color blindness in her family (i.e. she is homozygous dominant) marries a man with normal color vision. What are the likely genotypes and phenotypes of any children they have. (Note: your probability value should be given as a percentage - %) Briefly explain your answer
Question 131 pts If the alleles for different traits (eye and hair color) are on different chromosomes, then during anaphase of meiosis I and II, the chromosomes or eye and hair color can end up in different gametes. This is called _________________.

What is the father's genotype? a. not enough information to determine the father's genotype b. AB c. Bo 2. What are the chances that a couple will have a boy with colorblindness, sex-linked recessive if the father is colorblind and the mother is homozygous dominant for normal color vision? a. 0% b. 100% c. 75%...

please answer question 1-4 with a breif explanation thankyou 1. In humans, red-green color-blindness is a sex-linked (carried on the X chromosome) recessive trait. If a woman who is not color blind but whose father was color-blind marries a man who is not color-blind, what is the probability that their first child will be a daughter who is color- blind? a) 0 b) 25% c) 50%- d) 100%- e) cannot tell from the information given 2. In a certain species...
po 1 pour Part 3 - Pedigree Analysis (3 points) In humans, normal color vision vs. red-green color blindness is conditioned by alleles C (dominant normal) and c (recessive red-green color blind) at a sex-linked locus. A color-blind father and normal vision mother have three children. One daughter has normal vision; another daughter and son have red-green color-blindness. Draw the pedigree chart for this family, using the generally accepted symbols and including a legend, and indicate the genotypes of all...

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...
