Simple Punnett Square

This is an example of

• Complete dominance

• Mendelian Genetics

• Codominance

• Incomplete Dominance

Which of these Punnett squares represents a cross between a homozygous dominant parent and a heterozygous parent?

• 
• 
• 
• 

Incomplete dominance occurs in cats, which allows them to be Black, White, or gray as shown on this Punnett square. What percentage of the offspring will be black?

• 25

• 50

• 75

• 100

This diagram shows the possible genotypes and phenotypes for the offspring in a simple genetic cross.
What are the genotypes of the two parents in this genetic cross?

• One parent is TT; the other parent is Tt.

• One parent is TT; the other parent is tt.

• Both parents are short.

• Both parents are tall.
