Patterns of Inheritance Test Review

Who is known as the "father of genetics"?

• Charles Darwin

• Karl Ernst von Baer

• Gregor Mendel

• Francis Franklin

A HETEROZYGOUS individual would have the genotype:

• Hh

• hh

• HH

• Hi

In pea plants, tall (T) plant alleles are dominant to short (t) plant alleles. If two tall plants (each with the genotype Tt) are crossed, what is the probability that the cross would result in a short pea plant?

• 25%

• 50%

• 75%

• 100%

Patrick Star recently married Patti. He is considered a purebred for his tall head shape (T), which is dominant over a short head (t). If Patti is a short-headed woman, what type of heads would their children have? (HINT: do a Punnett Square on a piece of paper)

• 75% Tall and 25% short

• 25% Tall and 75% short

• 50% Tall and 50% short

• 100% Tall
