A heterozygous individual would have the genotype:

In humans, blue eyes are a recessive trait. What genotype would a blue eyed child have?

None of the above, brown eyes are dominant.

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%

The observable traits of an organism are known as its

allele

dominance

phenotype

genotype

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?

25%

50%

75%

Dominant alleles are represented by a(n)
