Dominant & Recessive Traits Vocab Review

Different versions of a gene are

• Genotypes

• Phenotypes

• Alleles

• None is correct

The stronger allele that is expressed when one or more copies are present is

• Dominant

• Recessive

• Homozygous

• Heterozygous

The weaker allele that is expressed only when two copies are present is

• dominant

• recessive

• genotype

• phenotype

The genetic makeup of an organism, expressed as a combination of letters is

• phenotype

• genotype

• incomplete dominance

• codominance

The physical characteristics expressed through alleles are

• genotypes

• phenotypes

• homozygous

• heterozygous

When two alleles for a trait are identical they are said to be

• heterozygous

• homozygous

• codominance

• incomplete dominance

If alleles for a trait are different they are said to be

• homozygous

• heterozygous

• codominant

• incomplete dominance

When neither allele is completely dominant and offspring are a blend of both alleles it is called

• homozygous

• heterozygous

• incomplete dominance

• codominance

When both alleles are dominant and offspring show both alleles at the same time it is called

• codominance

• incomplete dominance

• genotype

• dominant
