Heredity Practice Test

Changing the DNA that makes up a gene (used to produce large volumes of medicine and improve tomatoes).

• hybrids

• genetic engineering

• alleles

• recessive

Offspring that receives different genetic information for a trait from each parent.

• purebred

• hybrid

• genetic engineering

• multiple alleles

Different forms of a trait that a gene may have (one form of a gene)

• alleles

• hybrid

• purebred

• recessive

Offspring of 2 homozygous parents show an intermediate phenotype. (ex. you get a pink flower when you cross a red and white).

• multiple alleles

• genetic engineering

• incomplete dominance

• genes

Trait produced by a combination of many alleles.

• polygenic inheritance

• dominant

• genetic engineering

• sex-linked gene

Genetic makeup of an organism.

• phenotype

• genotype

• heterozygous

• homozygous

A trait that is covered over by another form of that trait and seems to disappear.

• dominant

• homozygous

• recessive

• retreat

The study of how traits are inherited through the interactions of alleles.

• genetics

• polygenic inheritance

• Punnett Square

• hybrid

Tool used to predict results in genetics.

• sex-linked gene

• recessive

• Punnett Square

• genetics

A trait that covers over, or dominates, another form of that trait.

• alleles

• dominant

• genetic

• recessive
