- Earlobes can be attached to the face or non-attached. An attached earlobe is a recessive trait. A female with attached earlobes (Il) has a child with a man with non-attached earlobes. He is heterozygous for this trait. Questions: a. What are the possible genotypes of the egg the woman can produce? b. What are the possible genotypes of the sperm the man can produce? c.

Parents Jacob and Emma have had two children, Samuel and Matthew. Baby Samuel died at the age of nine days. When baby Matthew has trouble feeding, his parents take him in to the doctor. He is diagnosed with Maple Syrup Urine Disease (MSUD), a life-threatening condition in which the patient is not able to break down proteins from 19 their food. As Matthew receives treatment, Jacob and Emma are referred to a genetic counselor. The genetic counselor collects information about their family. Neither of Jacob's parents were affected by MSUD. Jacob had one brother and three sisters. One of these sisters died shortly after birth. Similarly, neither of Emma's parents were affected by MSUD. Emma had four brothers, and two of these died shortly after birth. a. Given what you know about Jacob and Emma's family, construct a pedigree that includes all three generations.arrow_forwardMatch the mode of inheritance with its description.

The male is heterozygous for Huntington’s disease and homozygous dominant for Tay-Sachs. The female is homozygous recessive for Huntington’s disease and heterozygous for Tay-Sachs. The couple is curious about the possibility and probability of their offspring inheriting Tay-Sachs and/or Huntington’s. For humans, Huntington’s disease is dominant (H) over the “normal” condition (h), and the “normal” condition is dominant (T) over Tay-Sachs (t).

- 15. The following pedigree shows inheritance of Huntington's disease, a fatal genetic disorder that causes neurodegeneration. Since signs and symptoms usually do not appear until adulthood, many who are carriers may not realize their risk of passing on the disease-causing allele.
