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%

Each parent contributes one of the genes for a particular trait. The genes of the pair are called:

• variables
• gametes
• hybrids
• alleles

The gene makeup of an organism for a particular trait is known as its

• dominance
• phenotype
• allele
• genotype

What is the percentage of homozygous recessive offspring?

• 0%
• 25%
• 50%
• 75%

Dominant alleles are represented by a(n)

• phenotype
• lower case letter
• upper case letter
• punnett square
