- Lactose intolerance is a disorder caused from the inability to digest the sugar lactose. It is not an allergy to milk, but rather is due to the lack of a functional enzyme known as lactase. It is a dominant genetic disorder. A couple, both of whom are lactose intolerant, have two children who have no problem digesting milk or milk products. What are the chances that a third child will be lactose intolerant? 0% 25% 50% 75% 100%Sickle cell anemia is a genetically inherited autosomal recessive trait in which results in a condition that there are not enough healthy red blood cells to carry oxygen throughout the body due to the production of red blood cells that are sickle shaped. The frequency of the sickle cell condition is as high as 10% in Central Africa compared to 0.5% in the United States. Calculate the frequency of the normal and carries of the sickle cell condition.Two alleles for the same trait that are expressed equally are: OCodominant ODominant ORecessive OSex linked
- Write the genotype for each person based on : -Homozygous for B allele -Heterozygous for A allele -Type O -Type A and had a type O parent -Type AB -Blood that can be donated to anybody -Can only received blood from a type O donor There is a couple, the blood type of a male is A+ and the female is o+. What are all the possible blood types of their children in the future? Illustrate the inheritance in a Punnett Square showing all the possible blood types from the offspring of the male and female.Phenylketonuria (PKU) is an inheritable disorder whereby phenylalanine accumulates in the blood. If left untreated, the disorder can lead to severe health problems and intellectual disabilities.If individuals II-2 and II-8 had a child, what is the percentage chance that this child will suffer from PKU?Unattached earlobes is dominant to attached earlobes. Two parents, both with unattached earlobes, had a child with attached earlobes. What are the chances that their next child will have attached earlobes? 25% 50% 0% cannot be determined from this info
- A man that can roll his tongue is heterozygous for the trait marries a woman that cannot roll her tongue. They have a child. Rolling tongue is dominant to not rolling tongue. What is the probability of having a child that can roll their tongue? Cannot role their tongue? What is the man’s genotype for tongue rolling? The woman’s? Show the Punnett square for child’s genotype Give the probability (percent chance) that the child can or cannot roll their tongue.Using the two equations, p + q = 1 and p2 + 2pq + q2 = 1, answer the following question A Hispanic-American couple wants to know their risk for having a child with cystic fibrosis. One parent has no family history of disease, but the other parent has a sibling with cystic fibrosis. Calculate the conditional probability that the couple has a child with cystic fibrosis.The table below shows the blood types of mothers and children. Complete the table by filling in all the possible genotypes for the mother and child. For each given mother and child, list any genotypes that can be eliminated as possibilities for the father.

- Phenylketonuria (PKU) is an inheritable disorder whereby phenylalanine accumulates in the blood. If left untreated, the disorder can lead to severe health problems and intellectual disabilities. If individuals II-2 and II-8 had a child, what is the percent probability of them having children with PKU?Answer %Record your answer rounded to one decimal place.The following is a summary of the possible sickle-cell genotypes and phenotypes: AA - cojmpletely normal AS - sickle-cell trait (this person has a combination of normal hemoglobin and the abnormal, sickled form of hemoglobin) SS - sickle-cell anemia (all abnormal hemoglobin) Make a punnett square for help answering the question: What is the probability of a couple having a child with sickle-cell trait if one parent is normal and the other has sickle-cell trait?Classical hemophilia is a sex-linked disease caused by a recessive gene on the X chromosome. (Hemophilia refers to diseases that cause delays in blood clotting.) If a woman who is acarrierof classical hemophilia has children with a normal male, give the ratios of the possible offspring with respect to classical hemophilia. Be sure to state both the genotypes and the phenotypes of each offspring. For genotypes, use X for a normal X chromosome, Xh for an X chromosome with the hemophilia gene, and Y for a normal Y chromosome. For phenotypes, if the offspring is female, be sure to state if homozygous normal, a carrier, or has the disease. If the offspring is a male, be sure to state if normal or has the disease.
