Huntington's disease, which causes degeneration of neurons, runs in Mark's family. Huntington's is a heritable, autosomal dominant genetic disease. In an autosomal dominant disease, only one abnormal allele is required to cause the disease in offspring. However, it is possible that not all offspring will receive the abnormal allele from an affected heterozygous parent. Family members that have the disease include Mark's maternal grandfather and Mark's maternal aunts. Mark's maternal grandmother does not have the disease. Because symptoms of Huntington's disease do not appear until later in life, genetic testing is necessary to determine whether a younger individual possesses the allele for the disease. These tests determined that Mark's mother does not carry the allele for Huntington's disease. Mark's paternal aunt suggested that Mark create a pedigree to track the disease in his family. Use the symbols provided to complete the pedigree. Each symbol may be used more than once.
Answer:
The correct answer is - maternal grandmother unaffected, maternal father affected, two maternal aunts affected, mother not affected and paternal side not affected so Mark is also not affected. (check the image)
Explanation:
As we know Mark's paternal grandparents do not have Huntington's disease. If the grandparents are normal the father and paternal aunt of Mark does not carry the disease allele therefore the symbols on the right represent Mark's paternal family.
We also know that the grandfather from the maternal side is affected and maternal aunts also have Huntington's disease, it is found out by the genetic testing that the mother is unaffected which means Mark will be unaffected as well as mother and father both are normal.
2. A man has type A blood and his wife has type B blood. A physician types the blood of their four children
and finds that each of the children has a different blood type. What are the genotypes of the parents? How
would you explain that all four blood types could be represented by these four children?
Answer:
A person with type A blood receiving a transfusion of type B or AB blood would have an ABO incompatibility reaction. In an ABO incompatibility reaction, your immune system attacks the new blood cells and destroys them. If you have type AB blood, you have both A and B antigens .

If a flower is wilting, which structure inside its cells lacks water?
vacuole
cell wall
carpel
chloroplast
Answer:
Vacuole
Explanation:
The central vacuole stores water in the cell and helps maintain water pressure, or turgor pressure, within the cell. The plant wilts because the central vacuole is empty and the cell is partially collapsed. Once the plant is watered and the central vacuole is full again, the plant will return to its normal position and appearance.
