Normally when a person consumes a product that contains lactose (such as milk or cheese), the body breaks the sugar lactose down into galactose and glucose. Galactosemia is disorder caused by a missing or defective enzyme which ends up causing galactose to accumulate to poisonous and sometimes deadly levels. Galactosemia is a recessive disorder. If two individuals are heterozygous for this trait, what is the probability that their children WILL HAVE galactosemia?

In humans, there is a gene called sickle-cell anemia, which produces severe anemia when homozygous recessive. The name of the disease comes from the fact that many red blood cells take on abnormal sickle shape. People homozygous recessive for this trait usually die before adulthood. Heterozygous people appear normal, but when a sample of the blood is held under low oxygen concentration, the red cells take on the sickle shape. A young woman about to be married is concerned about her future children because her brother died of sickle-cell anemia. A sample of her blood sickles under low oxygen concentration, but that red blood of her perspective husband remains normal. What can you say about the woman and the man, and about their future children? HINT: Use Punnett square to help you and receive full credit

Which of the following genetic diseases is/are inherited as an autosomal recessive trait: phenylketonuria, Huntingtons disease, Tay-Sachs disease?
Knowing that individuals who are homozygous for the GD allele show no symptoms of galactosemia, is it surprising that galactosemia is a recessive disease? Why?
Hereditary hemochromatosis is an autosomal recessive genetic disorder that causes the body to absorb too much iron from the diet. This excess iron is stored in the body's tissues and organs, particularly the skin, heart, liver, pancreas, and joints. Because humans cannot increase the excretion of iron, excess iron can overload and eventually damage tissues and organs. Some individuals who are homozygous for this autosomal recessive gene experience only skin discoloration and joint pain, others experience heart disease in addition to the skin discoloration, still other individuals suffer also suffer from diabetes, severe heart disease, and liver damage. Name and define this genetic phenomenon and explain how it relates to this specific genetic situation described above.
Take the example of B-thalassemia, an autosomal recessive genetic disease that particularly affects people from around the Mediterranean. This disease is associated with an anomaly of hemoglobin, a protein essential for the transport of oxygen, which is composed of four chains: two alpha (a) and two beta (B). In case of B-thalassemia, the ẞ chains are produced in insufficient or no quantity in an individual homozygous recessive resulting in insufficient production of overall hemoglobin leading to anemia and other physiological challenges. The gene that controls the synthesis of the ẞ chains is located on chromosome 11. Here is part of the coding portion of this gene (which controls a total of 146 amino acids and of which you only see the portion 36 to 41) and one of the targeted mutations: 1. Give the sequence of amino acids from the template and mutated strands. 2. What type of point mutation is it? 3. Using the principles of the theory of evolution, explain briefly and generally why…
Acatalasia is caused by a rare autosomal recessive gene. In heterozygous condition catalase activity is decreased slightly. A woman with a normal catalase activity have a husband with low catalase activity. What is the probability of children birth without anomaly in the family, if grandparents from both sides have reduced activity of catalase? Diagram the cross and mention the genotypes of all individuals in the family?
Phenylketonuria is one of the most common recessive genetic disorders in humans. Infants with PKU are missing an enzyme called phenylalanine hydroxylase, needed to break down an amino acid called phenylalanine. If a strict diet that minimizes the amount of phenylalanine in the diet is not followed, a severe nervous disorder may result. If two heterozygous parents have a child, hah is the possible genotype and phenotype for this individual?
Salim and Sara are contemplating having children, but Salim’s brother has galactosemia and Sara’s great-grandmother also had galactosemia. Sara has a sister who has three children, none of whom is affected. What is the probability that Salim and Sara’s first child will have galactosemia? Explain your calculations.
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.
Phenylketonuria (PKU) is an inherited disease caused by a recessive allele. Individuals with PKU have two recessive alleles and have very low levels of an enzyme that is needed to properly break down proteins. If a woman and her husband are both carriers and have three children, what is the probability of each of the following? Show your math. (Hint: You can represent your probabilities as fractions or decimals, but probabilities are always between 0 and 1) a. All three children are of normal phenotype. b. One or more of the three children have the disease. c.All three children have the disease.
Pompe disease is a glycogen storage disorder caused by a lack of ⍺-glucosidase, the enzyme that converts glycogen to glucose in the muscles. Babies born with this disorder die by the age of two. pope disease is a genetic disorder caused by the presence of two recessive autosomal alleles. A. A man and a woman heterozygous for the condition have two female unaffected children. Determine, using a Punnett square, the probability, expressed as a whole number percentage, of a fourth baby being born a male with Pompe disease. B. Iftheman,fromthepreviousquestion,hadtypeAbloodandthewomanhadtypeO blood, what would be probability of them having a daughter with type O blood and affected with Pompe disease?
