Chapter 19, Problem 10CT
Bill and Marie each have flat feet, long eyelashes, and “achoo syndrome” (chronic sneezing). All are dominant traits. The genes for these traits each have two alleles, which we can designate as follows:
Bill is heterozygous for each trait. Marie is homozygous for all of them. What is Bill's genotype? What is Marie’s genotype? If they have four children, what is the probability that each child will have the same

Albinism is a recessive disorder where there is a lack of melanin. Andrea and her husband Claude both have normal skin pigmentation. Andrea’s mother has the albino phenotype, but her father and her brother do not (normal pigmentation). Claude’s parents are both normal, but he has a sister who has the condition (is albino). Answer the following questions
If Andrea and Claude are carriers for the albino allele, what is the probability that they have an albino child?
If Andrea and Claude have a second child, what is the probability this child be normal (non-albino)?
NOTE: Draw a punnet square or show your work.

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. Is the mother a carrier of the colorblindness allele? Please explain the meaning of the term "carrier", and answer this question, based upon all of the information provided.arrow_forward
