A colorblind make and a carrier female for color blindness. (But is not colorblind herself) have a child. Show your work! A) what is the % chance that their son will be color blind? B) what is the % chance that their daughter will be color blind?Two people are planning to have children together. Each person is heterozygous for the gene “G”. Using this letter, first list all the possible gametes that the two people can produce. Next, write all the possible genotypes and phenotypes for their offspring, using the correct genetic terminology (e.g., “genotype is homozygous dominant” “phenotype is dominant”). HINT: Use the gametes to construct a Punnett square and predict the possible offspring (you do not need to include the Punnett square in your answer
- The next three questions go together. Duchenne's muscular dystrophy (DMD) is a disease caused by a recessive allele at a gene on the X chromosome. Polydactyly is caused by a dominant allele at an autosomal gene. If a phenotypically normal woman who's father had DMD has a child with man who is heterozygous for the allele causing polydactyly but is otherwise normal, what is the probability that the child will have elther DMD or polydactyly, but not both?

Enter your answer to two decimal places leg. 0.88). Question 12 Part II: What is the probability that the child will have either DMD or polydactyly, but not both? Enter your answer to two decimal places (eg. 0.88).Two people are planning to have children together. Each person is heterozygous for the gene “A”. Using this letter, first list all the possible gametes that the two people can produce. Next, write all the possible genotypes and phenotypes for their offspring, using the correct genetic terminology (e.g., “genotype is homozygous dominant” “phenotype is dominant”). HINT: Use the gametes to construct a Punnett square and predict the possible offspring (you do not need to include the Punnett square in your answer).A couple with the following blood types: the man has type AB and the woman has type B, discover their child has type O blood. Is it possible that one of these ‘parents’ may not actually be the genetic parent of this child? If so, which one, and how do you know?

- Achondroplasia, which 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. What are the complete genotypes of the husband and of the wife with respect to both colorblindness AND achondroplasia. Please EXPLAIN your answer. Be sure to indicate which genotype is that of the husband and which is that of the wife.Achondroplasia, which is characterized by difficulty converting cartilage to bone and thus results in shortened limbs.
