Homework Answers
Answer:
Huntington's disease is caused by a. Nucleotide triplet repeat.
| Huntington |
disease is casued by HTT gene which contains a sequence of three DNA bases—cytosine-adenine guanine (CAG)—repeated multiple times (i.e. CAGCAGCAG ...), known as nucleotide triplet repeat. |

Huntington's disease is caused by the allele H, which is completely dominant to the normal recessive allele h. Consider a couple where the man has the genotype Hh, and the woman has the genotype hh. What is the chance that their first child will develop Huntington's disease? A. 0% B. 25% C. 75% D. 50%

10. Red green colorblindness is an X-linked recessive disease. That means that it is carried on the X chromosome, so men have just one copy of the gene while women have two. In women, both copies must be the recessive disease allele in order to show the disease phenotype, but because men only have one allele, just one recessive allele causes the disease phenotype. Matt and Kate both have normal vision, but Kate's father is colorblind. Use X for the...

Problem 3.3. In the above pedigree, the children with shaded box/circle suffer from a rare condition of having "fragile skin" as compared to the normal phenotype of skin. Is this fragile skin disease caused by a recessive or dominant allele? Now determine the genotype of both parents using alleles for normal skin and fragile skin, using S- dominant allele; s- recessive allells

8. [12 pts total] Huntington disease is a rare degenerative autosomal disorder that determined by a dominant allele. The disorder is typically manifested after the age of 45. A young man has learned that his father has developed the disease; his mother does not carry the dominant allele for the condition [4 pts] A. What is the probability that the young man will later develop the disease? (4 pts] B. If the young man has a child with a woman...

conditions
The pedigree from Part A is shown below. Fill in the most likely
genotypes of the indicated individuals in the pedigree. Note that a
dominant allele followed by an underscore (_) indicates that either
the dominant or the recessive allele may be present at the second
position. Drag one pink label (for condition A, autosomal

B, X-linked recessive) to each...
