- Phenylketonuria (PKU) is an autosomal recessive disease that results from a defect in an enzyme that normally metabolizes the amino acid phenylalanine; when this enzyme is defective, high levels of phenylalanine cause brain damage, in the past, most children with PKU became intellectually disabled. Fortunately, intellectual disability can be prevented in these children by carefully controlling the amount of phenylalanine in the diet. The diet is usually applied during childhood when the brain development is taking place. As a result of this treatment, many people with PKU now reach reproductive age. Children born to women with PKU (who are no longer on a phenylalanine-restricted diet) frequently have low birth weight, developmental abnormalities, and intellectual disabilities. However, children of men with PKU do not have these problems. Describe the results depicted in Fg1. and us it to provide an explanation for these observations What type of genetic effect is…arrow_forwardPhenylketonuria (PKU) is a human hereditary disease resulting from the inability of the body to process the chemical phenylalanine, which is contained in the protein we eat. PKU is manifest in early infancy and, if it remains untreated, generally leads to cognitive impairment. PKU is caused by a recessive allele with simple Mendelian inheritance. A couple intends to have children but consults a genetic counselor because the man has a sister with PKU and the woman has a brother with PKU. There are no other known cases in their families. They ask the genetic counselor to determine the probability that their first child will have PKU. What is this probability?arrow_forwardparents, but her brother Alonzo has Galactosemia. Brice has a similar family history. He and his parents are healthy, but his sister Brianna has galactose, a component of the lactose found in mammalian milk. Galactosemia can be galactosemia. Amanda and Brice are planning on marrying and starting a family and partially managed by eliminating dietary intake of lactose and galactose.

- Achondroplasia is an autosomal dominant disorder characterized by disproportionate short stature: the legs and arms of people with achondroplasia are short compared with the head and trunk. The disorder is due to a base substitution in the gene, located on the short arm of chromosome 4, that encodes fibroblast growth factor receptor 3 (FGFR3). Although achondroplasia is clearly inherited as an autosomal dominant trait, more than 80% of the people who have achondroplasia are born to parents with normal stature. This high percentage indicates that most cases are caused by newly arising mutations; these cases (not inherited from an affected parent) are referred to as sporadic. Studies have demonstrated that sporadic cases of achondroplasia are almost always caused by mutations inherited from the father (paternal mutations). In addition, the occurrence of achondroplasia is higher among the children of older fathers; approximately 50% of children with achondroplasia are born to fathers…arrow_forwardLactose intolerance is inherited through a recessive allele. A husband and wife both digest lactose properly. However, the wife's Mom is lactose intolerant. The husband's Dad is also lactose intolerant. What is the probability this couple will have children with a lactose intolerance problem?arrow_forwardPhenylketonuria 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?arrow_forward
- 1a) Explain how amino acids in casein could reach the liver, starting fromthe moment when the person takes a bite of pastry cream pie. b) Congenital lactase deficiency is a type of lactose intolerance that occursin infants. It is inherited in an autosomal recessive pattern. Calculate thechance of congenital lactose intolerance in a child whose parents are both carriersfor the disorder, showing fully how you reached your answer.arrow_forwardSickle cell anemia is inherited as an autosomal recessive condition. It also exhibits incomplete dominance in that the heterozygous genotype displays a mild form of the disease known as sickle cell trait while individuals with the homozygous recessive genotype have a severe form of SCA. A man who has severe sickle cell anemia marries a woman who suffers from a mild trait. What is the probabilitu they will have a child with severe SCA?What is the probability they will have a child with mild SCA? What is the probability they will have a normal child? Show ALL work using punnett squares.arrow_forwardGalactosemia is a metabolic condition, caused by a recessive allele, which prevents affected patients from breaking down certain sugars. In infants galactosemia can lead to a toxic build-up of the by- product galactol, but negative effects can be minimized if the condition is identified early and the child is kept on a diet free from lactose or galactose. John and Maggie both know they are carriers of the galactosemia allele. They have just been married and hope to start a large family. If they have four children, what is the chance that none of them will be affected by the disease? (4 points)arrow_forward
- Neurofibromatosis-1 (NF1) is an autosomal dominant disorder where tumours form in the base layer of the skin or in nerve tissues. What is the probability that individuals II-1 and II-2 will have a genetic son with NF1? Find the image attached.arrow_forwardOne of your patients, a six-year-old girl who suffers from Sickle cell anemia, an inherited blood disorder in which red blood cells are abnormally shaped and fragile, leading to a short supply of red blood cells. These abnormal cells can also get stuck in small vessels, which prevent blood flow, leading to fatigue, pain and other severe complications. Sickle cell anemia is an autosomal recessive disorder. Neither of your patient's parents has sickle cell anemia. What is the most likely genotype of her parents? (The normal beta-globin allele is abbreviated as B, and the abnormal allele as b.) one is B and one is b one is BB and one is bb both are Bb both are bb both are BBarrow_forwardCystic fibrosis (CF) is an autosomal recessive condition triggered by the overproduction of stickymucus that clogs the lungs and pancreas. It is a life-threatening disease, but medical advances helpedthe afflicted to live through adulthood.The mother of Claudia died from cystic fibrosis, but her father was normal and never had anyrelative with CF. Her fiancé, Marcus, turned out to be a carrier of the CF allele. What are the genotypes of Claudia and Marcus?
