A.
To determine: The pedigree for the given condition.
Introduction: Galactosemia is a limited genetic
B.
To determine: The probability that this child will have galactosemia.
Introduction: Galactosemia is an autosomal recessive disease. An autosomal illness is a condition that does not depends on the sex chromosomes. If two people who possess galactosemia have children, all of them will have galactosemia.
C.
To determine: If the first child has galactosemia, the probability that a second child will also be having the same condition.
Introduction: An autosomal recessive disorder indicates both copies of the gene in every cell need to hold the mutation for a person to exhibit indications. The parents of an affected person typically bear one copy of the abnormal gene, though they do not show symptoms of galactosemia.

- 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.

A hemophilic man who is also homozygous for baldness has children with a woman who carries normal genes for both traits. What is the probability that any of their child will be: a.

What is the most likely explanation? b. Diagram the cross between the woman and her husband using a Punnett square, give the genotypic ratio (GR) and phenotypic ratio (PR) from the Punnett square. c. Based on the Punnett square results, what is the chance that her next child will have the disorder?arrow_forwardGlucose-6-phosphate dehydrogenase (G6PD) deficiency is a disorder that affects the normal function of red blood cells and can eventually lead to anemia. The trait is controlled by a recessive allele found on 4. the X chromosome. An affected son was born to a man and woman who were unaffected. The woman's mother was affected while the father was normal. a. Indicate the gene notation. b. Give the genotypes of the affected boy's parents.

The following pedigree shows inheritance of Huntington's disease, a fatal genetic disorder that causes neurodegeneration.
