- A type of red-green colorblindness is inherited recessively on the X chromosome. A woman who is a carrier had children with a male that is not affected by the disease. Show your answers with the use of a Punnett square • What is the probability (% or likelihood) that a child is affected by the disease? • What is the probability (% or likelihood) that a son is a carrier? (Careful!) • Is there a chance that a girl of the couple is affected by the disease?Given that a human normally contains 46 chromosomes, give the chromosome number for each of the following conditions: Turner syndrome (female, no Barr bodies): Klinefelter syndrome (male, one Barr body): Triploid: Down syndrome (trisomic): Trisomy 13:Imagine a cross between a man and a woman having the following genotypes: Genotype of the Husband Genotype of the Wife Aa bb Dd Gg Hh RR Tt X Aa Bb Dd gg Hh Rr Tt Assuming that the dominant allele in each gene pair exhibits complete dominance over the recessive allele, what is the probability that this couple would have a daughter who exhibits the recessive phenotype with respect to all seven of the gene pairs?
- A woman homozygous dominant for albinism marries a man who is homozygous recessive for albinism. What are the possible genotypes and phenotypes percentages for their offspring?The most common form of colorblindness is a recessive, sex-linked hereditary con dition caused by a defect on the X chromosome. Females are XX, while males are XY. Individuals inherit one chromosome from each parent, with equal probability; for example, an individual has a 50% chance of inheriting their father's X chromosome, and a 50% chance of inheriting their father's Y chromosome. If a male has an X chromosome with the defect, he is colorblind. However, a female with only one defective X chromo some will not be colorblind. Thus, colorblindness is more common in males than females; 7% of males are colorblind but only 0.5% of females are colorblind. (a) Assume that the X chromosome with the wild-type allele is X+ and the one with the disease allele is X. What is the expected frequency of each possible female genotype: X+X+, X+X¯, and X-X-? What is the expected frequency of each possible male genotype: X+ Y and X-Y? (b) Suppose that two parents are not colorblind. What is the…A karyotype shows that a child has Klinefelter syndrome (47,XXY). If the child is also colorblind (due to a recessive X-linked allele), despite his parents having normal color vision, in which parent and stage of meiosis did nondisjunction occur? And explain why .
- If a father has Marfan syndrome, a dominant disorder, and passes it down to all of his children, but his wife does not have the disorder, what would the punnett square between the father and mother look like? Why is this his genotype if all of his children had Marfan syndrome?A woman homozygous dominant for albinism marries a man who is homozygous recessive for albinism. What are the possible genotypes and phenotypes for their offspring? What are the ratios?Cystic fibrosis is a genetic disease that causes an abnormal production of mucus which in turn can cause damage and infection to the lungs and other organs. In the following pedigree, black indicates all those persons afflicted with cystic fibrosis (square symbols are males, circles are females). There's a healthy couple and they have two children. One is a 23-year-old daughter with cystic fibrosis who is married to a 24-year-old male who is healthy. The other child is a 15-year-old son who is healthy After studying the pedigree, write a logical hypothesis suggesting the cause of cystic fibrosis in terms of dominant or recessive alleles. On the basis of your hypothesis, write an appropriate genotype for both of the parents. Using a Punnett square, what is the probability of the parents having a child with cystic fibrosis? If the daughter's husband is a carrier of cystic fibrosis, what is the probability that they have a child with cystic fibrosis? Show your Punnett square.
- Hemophilia is a disease caused by a gene found on the X chromosome. Therefore, it is a sex-linked disease which is caused by the recessive allele. Suppose, a man with hemophilia marries a woman who is homozygous dominant for the trait, what is the chance of having children who are hemophiliacs? (XH = normal; Xh= hemophiliac) * a. 0% b. 75% c. 100% d. 25%In the following pedigree of an X-linked recessive trait, what is the likelihood a child will be affected for the following matings? 1 x 2 [___] 13 x 14 [_____] 2 x 14 [_______] 4 x 12. [_______]A woman with blonde hair and blues eyes, which are recessive genes, marries a heterozygous man who has brown hair and eyes. What are the possible genotypes and phenotypes of their children?
