Concept #2: Steps to Performing a Test Cross

Practice: To identify the genotype of a yellow-seeded pea plant as either homozygous dominant (YY) or heterozygous (Yy), you could do a test cross between your mystery plant and a plant with a genotype of _______.

a) YY. 

b) yY. 

c) Yy. 

d) yy.

Practice: A single gene test cross is conducted to determine the genotype of a pea plant that shows the dominant phenotype for height (T = tall, t = short). If all offspring of the cross show the dominant phenotype, then the genotype of the unknown parent is _______.

a) TT.

b) tT. 

c) Tt. 

d) tt.

Practice: You want to determine the pea color genotype of a pea plant with yellow peas. You conduct a test cross with your mystery pea plant. The test cross results in 50% of the offspring possessing yellow peas and 50% of the offspring possessing green peas. What is the genotype for pea color of the mystery parent?

a) YY.

b) Yy.

c) yy.

d) None of the above.
