Introduction:
Scientists study family history using a diagram that traces inheritance of a particular trait through several generations. Such diagrams are called pedigree. A pedigree uses symbols to illustrate the inheritance of trait. By analyzing the pedigree we can infer the genotypes by observing the
Answer to Problem 5A
Correct answer :
The correct answer is option D. Huntington’s disease
Explanation of Solution
Explanation/justification for the correct answer:
Option D. Huntington’s disease - The given pedigree illustrates inheritance of a rare genetic disorder. In this diagram, some express the disease and some do not have the disease. There are no circles or squares which are half filled; so there are no carriers of the disease. Hence we can say that the disorder is a dominant genetic disorder because a recessive genetic disorder will have a carrier. Amongst the diseases given only Huntington’s disease is a dominant genetic disease. The other three are recessive genetic disorders.
Hence this is the correct option.
Explanation for incorrect answer:
Option A. cystic fibrosis- It is a recessive genetic disorder. Since the given pedigree does not show any carrier of the disease, it may be concluded that the pedigree shows a dominant genetic disorder. Hence this is not the correct option.
Option B. albinism- It is a recessive genetic disorder. Since the given pedigree does not show any carrier of the disease, it may be concluded that the pedigree shows a dominant genetic disorder. Hence this is not the correct option.
Option C. Tay-Sachs disease- It is a recessive genetic disorder. Since the given pedigree does not show any carrier of the disease, it may be concluded that the pedigree shows a dominant genetic disorder. Hence this is not the correct option.

- "One of the symmetry breaking events in mouse gastrulation requires the amplification of Nodal on the side of the embryo opposite to the Anterior Visceral Endoderm (AVE). Describe one way by which Nodal gets amplified in this region." My understanding of this is that there are a few ways nodal is amplified though I'm not sure if this is specifically occurs on the opposite side of the AVE. 1. pronodal cleaved by protease -> active nodal 2. Nodal -> BMP4 -> Wnt-> nodal 3. Nodal-> Nodal, Fox1 binding site 4. BMP4 on outside-> nodal Are all of these occuring opposite to AVE?arrow_forwardIf four babies are born on a given day What is the chance all four will be girls?

- Plekhg5 functions in bottle cell formation, and Shroom3 functions in neural plate closure, yet the phenotype of injecting mRNA of each into the animal pole of a fertilized egg is very similar. What is the phenotype, and why is the phenotype so similar? Is the phenotype going to be that there is a disruption of the formation of the neural tube for both of these because bottle cell formation is necessary for the neural plate to fold in forming the neural tube and Shroom3 is further needed to close the neural plate? So since both Plekhg5 and Shroom3 are used in forming the neural tube, injecting the mRNA will just lead to neural tube deformity?arrow_forwardWhat are some medical issues or health trends that may have a direct link to the idea of keeping fat out of diets?arrow_forwardwhat did charles darwin do in sciencearrow_forward
