Considering a common autosomal recessive trait: (Read each statement carefully. Select all of the statements below that are true (that you agree with). Leave any statements that are false (that you do not agree with) un- selected.) the unaffected biological siblings of an affected person should be heterozygotes. an unaffected woman and an affected man have at most a 100% probability of having a affected child. an affected person should have an affected parent.

A pedigree analysis was performed on the family of a man with schizophrenia. Based on the known concordance statistics, would his MZ twin be at high risk for the disease? Would the twins risk decrease if he were raised in an environment different from that of his schizophrenic brother?
Bryan has albinism, an autosomal recessive trait, which means he is homozygous recessive for albinism and his genotype is aa. Bryan's parents, Frank and Amy, do not have albinism however they must both be heterozygous. Bryan's sister, Allice, is a carrier for albinism. If Allice has offspring with Jim, who has no family history of albinism, what are the chances that their offspring are carriers for albinism? What are the chances that they children will get albinism? Use Punnett squares.
If an individual is bald, so you can't tell whether or not they have a widow's peak, but neither parent has a widow's peak, which genotypes are possible? Unable to determine Heterozygous Homozygous recessive Homozygous dominant
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.

People with recessive disorders are usually born to normal parents who are both heterozygotes which means that both parents are carriers of the dominant allele for the disorder but appear normal themselves. Select one: True False
Huntington’s disease, a neurodegenerative genetic disorder that typically becomes noticeable in middle age, is due to an autosomal dominant allele. Sickle cell anemia, on the other hand, is a genetic blood disorder due to a recessive allele. Mary is a carrier of the allele for sickle cell anemia but has no sign of any neurodegenerative disorder in her family. She married Paul whose father died of Huntington’s disease. His mother, however, is not inflicted with that condition. Neither of his parents exhibits sickle cell anemia. What are the genotypes of Jane and Paul? If they plan to have four children, what is the probability that: all their children will be normal? _________________________________ they will have a son with Huntington’s disease? _________________________ they will have a daughter inflicted with both conditions?________________
Assume for a moment that a child has a autosomal recessive disorder, but both parents appear normal. What is the genotype of both parents? : one parent must be homozygous dominant : both parents must be homozygous recessive : both parents are heterozygous : both parents nust be homozygous dominant
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.
Mary and Dai both have freckles (a dominant trait). Their first child, Mariko, does not have freckles. Show using a Punnett square show how this is possible. If they have two more children who DO freckles (making for one without and two with) what is the probability that the NEXT child will NOT have freckles?
Martin and Sue are contemplating having children, but Martin’s brother has an autosomal recessive disease and Sue’s great-grandmother also had the same disease. Sue has a sister who has three normal, healthy children. What is the probability that Martin and Sue’s first child will have the autosomal recessive disease? HINT draws out pedigree charts and punnett squares for Martin and Sue.
Hillary is 8 years old and has neuronal ceroid lipofuscinosis, also known as Batten disease. It is autosomal recessive and always affects children before the age of 2. Her parents are not affected.
