1.    In peas, seeds can be round (R) or wrinkled (r) and either yellow (Y) or green (y). A heterozygous round, green individual is crossed with a wrinkled, heterozygous yellow individual.

a.    What are the genotypes of the parents? What are the gametes produced from the parents? (use the FOIL method for this, no need to show the FOIL solution; 2 pts)

b.    What is the possibility of obtaining a wrinkled, green individual? Show the Punnett square solution. (3 pts)

1.    In humans, color blindness is a recessive, sex-linked trait. A colorblind father is married to a normal, carrier mother. Show the Punnett square solution below, and determine the possibility of obtaining the following offsprings: (only 1 Punnett square solution needed; 2 pts for the Punnett square solution)

Punette square:

a.    A female, colorblind offspring (1 pt)

b.    A male, normal offspring (1 pt)

c.     A male, colorblind offspring (1 pt)

1. Jin has blood type A. He marries Anna who has blood type B. They have four children, and all the blood types are represented in the children’s blood types (type A, B, AB, and O).

a.    What are the genotypes of Jin and Anna?

b.    Draw a Punnett square solution that shows how the genotypes of the children were made possible.

1.    In humans, Tay Sachs disease is a disorder is a recessive disease that causes an absence of enzymes needed to break down fatty substances. However, even if it is a recessive disorder, heterozygous individuals have a “partial manifestation” of Tay Sachs disease, where-in these individuals are able to produce half of the enzymes needed by the body, therefore making them normal individuals. Use the letter H to represent the traits.

a.    What type of inheritance is shown by Tay Sachs? Explain in not more than 5 sentences.
