- A couple seeks advice from a genetic counselor because they know that they are both carriers for cystic fibrosis (which is autosomal recessive), and the woman is a carrier for Duchenne muscular dystrophy (which is sex-linked recessive). For each of their future sons and daughters (calculate separately), what is the probability that they will be affected for: Both cystic fibrosis and nuscular dystrophy If the couple’s first born son has both cystic fibrosis and muscular dystrophy, what is the probability that their second born son will have both diseases?A couple seeks advice from a genetic counselor because they know that they are both carriers for cystic fibrosis (which is autosomal recessive), and the woman is a carrier for Duchenne muscular dystrophy (which is sex-linked recessive).

Unfortunately, their son Albus is affected with this condition. What are the chances that Ginny and Harry's next child will be a carrier for PKU? O 50% O 25% O 100% O 75% O 0%
- The autosomal (not X-linked) gene for brachydactyly, short fingers, is dominant to normal finger length. Assume that a female with brachydactyly in the heterozygous condition is married to a man with normal fingers. What is the probability that their first child will be a brachydactylous girl? ¼ 1/2 1/8 3/4 2/3In addition to the allelic pair determining pattern baldness in man (B,b), consider early baldness to be due to another autosomal allele (E) on a different pair of chromosomes and also dominant in males but recessive in females. The phenotype for ee may be late or nonbaldness depending on sex and the genotype for B, b alleles. Two doubly heterozygous persons marry. What is the phenotype of the male parent? What is the phenotype of the female parent? Give the phenotypic ratio expected among male children of couples such as this one. Show corresponding genotypes for each phenotype mentioned in your phenotypic ratio. Give the phenotypic ratio expected among female children of couples such as this one. Show corresponding genotypes for each phenotype mentioned in your phenotypic ratio.Albinism is an autosomal recessive condition characterized by absence of melanin pigment from the skin, eye and hair. Two carriers of albinism marry and plan to have FIVE children. Assume a 1:1 sex ratio. What is the probability that at least 3 children will be normal?
- Imagine that a couple is planning to have children. The male is heterozygous for Huntington’s disease and homozygous dominant for Tay-Sachs. The female is homozygous recessive for Huntington’s disease and heterozygous for Tay-Sachs. The couple is curious about the possibility and probability of their offspring inheriting Tay-Sachs and/or Huntington’s. For humans, Huntington’s disease is dominant (H) over the “normal” condition (h), and the “normal” condition is dominant (T) over Tay-Sachs (t). Complete a Punnett square for this cross and record the probabilities for genotypes and phenotypes of the offspring as ratios.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 boy with cystic fibrosis (a recessive disorder) is born to a couple who appear to be normal. What are the chance (percent or ratio) that any other children born to this couple will also have cystic fibrosis?
- Cystic Fibrosis is an autosomal recessive disorder. A couple are both carriers of the recessive allele (both heterozygous (Cc)) and have the normal wild-type phenotype. What is the probability of the following occurring; If they have one child, what is the probability of it having cystic fibrosis (cc)?If this is an autosomal recessive disorder, what is the probability that the first child of individuals III-1 and III-6 will be affected? 1Albinism and sickle cell anemia are both autosomal recessive disorders that are expressed only in the homozygous state. Two parents who are carriers for both albinism and sickle cell anemia plan to have a child. What is the probability that the child will have exactly one of the conditions? 3/8 7/16 O 1/16 O 1/4 9/16
