• genotype
• dominant alleles
• phenotype

When an organism has two alleles at a particular locus that are different, the organism is called

• purebred
• dominant
• heterozygous
• recessive

If a pea plant were homozygous recessive for height, how would its alleles be represented?

• Tt
• TT
• tt
• tT

An allele is dominant in a heterozygote when it is

• expressed and the other allele is not
• a very common allele in the population
• the stronger of the two alleles
• more desirable than the other allele

A distinguishing characteristic that can be inherited is a(n)

• cross
• allele
• gene
• trait

All of the genetic material that make up an organism is its

• gamete
• genome
• phenotype
• testcross

When is a recessive allele expressed in offspring?

• when two copies are present
• when parents have no dominant alleles
• when the offspring is heterozygous
• when one copy is present

To be considered members of the same species, organisms must be able to

• look alike
• reproduce together and have fertile offspring
• live in the same habitat
• eat the same types of food

Pelvic bones in snakes are an example of a(n)

• homologous structure
• analogous structure
• vestigial structure
