ESSAY SECTION
INSTRUCTIONS: Complete questions in this Essay Section – there are five (5) questions. Answer all questions.
1. A young male, is afflicted with a muscle wasting disease. His mother’s two brothers also had the disease. No other family members (his father, his father’s relatives, his mother, or his mother’s female relatives) have the disease. Is this muscle wasting disease (A) autosomal or sex-linked, and (B) dominant or recessive? Defend your answers.
2. Explain why the role of oxytocin in labor is an example of positive feedback. Do any other roles of oxytocin exhibit this same principle?
3. A young girl has a rare disorder in which she does not produce memory cells. What are memory cells, and what will likely be the effect of this disorder on her overall health?
4. Explain why the heart is described as a double pump. Provide specifics and use the correct technical terms in your answer.
5. Draw/diagram a Punnett square in which, upper case Tt represents two sets of genes (alleles) for a female with normal height, Tall female and lower case tt represents two sets of genes (alleles) for a short male. Note that upper case T represents a dominant trait—tallness and lower case t represents the recessive trait—shortness.
In this scenario, the female is tall in appearance (phenotype) and the male is short in appearance (phenotype).
i) Given that the female carries both genes (alleles), that is T and t, for height, explain why her appearance is tall.
ii) Next, draw a Punnett square for the offspring that could be produced from the union of this female Tt and this male tt.
iii) After drawing the Punnett square, discuss the phenotypes (appearances) of the four representative offspring whose genotypes are provided in the Punnett Square.
