Question
Red-green color blindness is an X-linked recessive trait in humans. Polydactyly (extra
fingers and toes) is an autosomal dominant trait. Martha has normal fingers and toes and normal
color vision. Her mother is normal in all respects, but her father is color blind and
polydactylous. Bill is color blind and polydactylous. His mother has a normal color vision and
normal fingers and toes. If Bill and Martha marry, what types and proportions of children can
they produce?

- Chloe has a family history of colorblindness. Corry, her partner, is affected by colorblindness. Colorblindness is an X-linked recessive condition that has the alleles XB which means -unaffected and dominant- and Xb which means -affected and recessive-. Chloe’s mom was affected, but her dad was not. Her partner Corry is also affected. (a)What is the probability that if Chloe and Corry were to have a daughter that she would be affected? (b)Also, what are the chances that if they had a son that he would be affected? Answer (a) and (b) by creating a pedigree and punnet squaresarrow_forwardA colorblind man marries a female who is a carrier for colorblindness. What is the probability that they will have a child who is colorblind?arrow_forwardHemophilia, disease in which the blood lacks a clotting factor, is caused by an X linked recessive gene. Joe doe not have hemophilia and Lucille is heterozygous for the condition. What is the chance that their MALE child will have hemophilia? (Note: you are calculating the probability for their MALE children only, in other words if they have 1 male child, what is the probability that he will be born with the disease?) 0% 1/4 or 25% 2/4 or 50% 3/4 or 75% 4/4 or 100%arrow_forward
- A certain type of deafness in humans is inherited as an X-linked recessive trait. A man with this type of deafness married a normal woman, and they are expecting a child. They find out that they are distantly related. Part of the family tree is shown here.How would you advise the parents about the probability of their child being a deaf boy, a deaf girl, a normal boy, or a normal girl? Be sure to state any assumptions that you make.arrow_forwardAdenike and her partner, Debare, are expecting their first child. Adenike is healthy as are her two sisters but her brother has PKU, a recessive disorder of the PAH gene. Genotypically he must be pah-/pah-. Neither of Adenike's parents has PKU but both of her grandmothers did. Debare is a carrier of Sickle Cell trait, which means he has one allele for wildtype hemoglobin (HbA) and one allele for Sickle Cell (HbS), making him HgA/HbS. More importantly, he has two alleles for Marfan Syndrome, a pleiotropic dominant disorder that can affect up to 30 different traits (M+/M+). No one in Debare's family has ever had PKU and no one in Adenike’s family has ever had Sickle Cell or Marfan Syndrome. They consult a genetics counselor over concern of the health of their baby. The genetics counselor collects the medical histories of three generations; their grandparents, their parents, and them. In her calculations, she produces a phenotypic key that indicates M = Marfan, Hb = sickle cell, and pah-…arrow_forwardAchondroplasia,is characterized by difficulty converting cartilage to bone and thus results in shortened limbs. This trait is autosomal dominant. (A = achondroplasia allele; a = average height allele.) A husband and wife both have achondroplasia. The couple have a total 12 living children: 6 boys and 6 girls. The husband is colorblind, which is an X-linked recessive trait, and the wife believes there is a chance she is a carrier of colorblindness, since that trait runs in her family. One of the couple’s daughters and three of their sons are colorblind. (Xc = colorblindness allele; XC = normal color vision allele.) a) Please list all of the different gametes that the husband can produce. b) Please list all of the different gametes that the wife can produce.arrow_forward
- Armin and Annie are going to have a baby. Annie has dimples in her cheeks (a dominant trait), while Armin does not. You know that Annie's father has dimples in both cheeks, while her mother does not. Her mother must have the recessive trait. Annie's father has the dominant trait, but you don’t know if he is a homozygote or heterozygote. But you still know what Annie’s genotype must be because Annie must have a recessive allele since that is all she could have inherited from her mother. Since Annie has a dimples you know she inherited a dominant allele from her father. What are the chances Armin and Annie’s baby will have dimples? Determine the Phenotype and Genotype and its probability.arrow_forwardAlbinism in humans is autosomal and fully recessive to normal color. A couple, who are both normal, have a daughter who is albino and a son who is normal. What is the probability that their normal son is a carrier of the albinism gene?arrow_forwardHemophilia is an X-linked recessive disorder that results in an individual not having a functional gene for a clotting factor and therefore unable to clot blood. A couple has 4 boys. One of the boys has just been diagnosed with hemophilia. What is the probability that all of the other 3 boys will also have hemophilia?arrow_forward
- In human beings, the gene for red‑green colorblindness (r) is sex‑linked and recessive to its allele for normal vision (R), while the gene for freckles (F) is autosomal and dominant over its allele for nonfreckled (f). A nonfreckled, normal‑visioned woman whose father was freckled and colorblind, marries a freckled, colorblind man whose mother was nonfreckled. What is the probability that the first child born to the couple will either be a freckled, colorblind boy or a non‑freckled, normal visioned girl or a non-freckled, normal visioned boy? What is the probability that the first four children born to the couple will be freckled and normal visioned girls?arrow_forwardAdenike and her partner, Debare, are expecting their first child.

A woman with blue eyes and normal color vision (her father was colorblind) marries a man who has normal color vision. The man has brown eyes, but his mother had blue eyes. What is the probability that this couple will have a child with normal vision and blue eyes?arrow_forward
