- A woman without red-green colorblindness and with a normal chin, whose mother was colorblind, marries a cleft-chinned, non-colorblind man whose mother had a normal chin. Recall that red-green colorblindness is sex-linked recessive, but mid-chin fissure (cleft) is autosomal dominant. What are the expected phenotypic ratios of the children? Show your work.A newly-married couple is thinking of having children. They are worried about their child having cystic fibrosis, a recessive disease that shows up in children with the genotype ff. Jake, the father is homozygous dominant with a genotype FF. Amy, the mother, is heterozygous with a genotype Ff. Should they be worried about their children having this disease? For full credit, discuss the probability of having each genotype (FF, Ff, and ff) in your explanation. You may first write and then RECORD YOUR ANSWER.Albinism is an autosomal (not sex-linked) recessive trait. A man and woman are both of normal pigmentation and have one child out of three who is albino (without melanin pigmentation). What are the genotypes of the albino's parents? One parent must be homozygous for the recessive allele; the other parent can be homozygous dominant, homozygous recessive, or heterozygous. Both parents must be homozygous dominant. One parent must be heterozygous; the other parent can be homozygous dominant, homozygous recessive, or heterozygous. Both parents must be heterozygous. One parent must be homozygous dominant; the other parent must be heterozygous. O000
- Hemophilia is a sex-linked recessive trait. A male hemophiliac and phenotypically normal female have a son with hemophilia. They would like to have one more child. What is the probability of having a child without hemophilia? Explain using a Punnett square. Is it possible for a girl to be born with hemophilia? Explain.Dimples (D) are a dominant trait genetic trait. Complete a Punnett Square to determine the possible phenotypes and genotypes of a cross between a man who is homozygous dominant and a heterozygous woman. Choose the percentages correctly below. Dimples: 0% 25% 50% 75% 100% No dimples: 0% 25% 50% 75% 100% DD: 0% 25% 50% 75% 100% Dd: 0% 25% 50% 75% 100% dd: 0% 25% 50% 75% 100%hemophilia is a sex linked recessive disease. Dick does not have hemophilia. His wife Debi is a heterozygote. They are having fraternal twins, one of each sex, who they have named Dick Jr. and Debi Jr. What are the chances of Dick Jr. having hemophilia? Debi Jr.?
- 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?Achondroplasia, 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. 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.Achondroplasia,is characterized by difficulty converting cartilage to bone and thus results in shortened limbs.

- Mary and Ron don't have albinism. However, is it possible for them to have a child with albinism? Explain. Stephanie has normal color vision. Her husband Chris also has normal color vision. They have a son that is color blind and a daughter that has normal color vision. What is the genotype of the mother, father, son and the daughter? Andy and Anne do not have polydactyl. Is it possible for them to have a child with polydactyl? Explain. When examining a pedigree chart, I notice that only males are affected. What does this tell me about the inheritance pattern? A man with blood type A marries a woman with blood type B. Their child has blood type O. What are the genotypes of the parents?Both red/green color blindness (R=normal, r=colorblind) and Duchenne-type muscular dystrophy (D=normal, d=muscular dystrophy) are X-linked recessive traits that map close to each other. A woman has a father who is red/green color blind. Her mother's family has a history of Duchenne's muscular dystrophy. This woman is apparently healthy with neither color blindness nor muscular dystrophy. She marries a healthy man and they have four sons and two daughters. Half the sons are healthy but color blind, the other half have normal color vision, but have Duchenne's muscular dystrophy. The daughters are both normal. What is the genotype of the woman? ** The notation is written as X/X (so the / separates the two X chromosomes in a female) Group of answer choices RD/rd rd/rd Rd/rD RD/RDHemophilia is an X-linked recessive disorder and blood type is autosomal. If two healthy parents, one of which is blood type A and the other blood type B, produce a son who has hemophilia and is type O, what is the probability that their next child will be a son with hemophilia and blood type B? 1/2 3/16 1/4 1/8 1/16
