Genetics Review

This term is used to describe one of the alternative forms of a gene that governs a trait

• genotype

• phenotype

• allele

• gene

This term describes the allele that is fully expressed in an organism’s phenotype if present

• homozygous

• heterozygous

• dominant

• recessive

This is a diagram that shows the how a trait is inherited over several generations

• Punnett square

• pedigree

• karyotype

• family tree

This law states that one of the factors for a pair of inherited traits will be dominant and the other recessive, unless both factors are recessive

• law of segregation

• law of incomplete dominance

• law of independent assortment

• law of dominance

This law states that all alleles of a gene occur in pairs, which separate from each other during the formation of sex cells

• law of segregation

• law of incomplete dominance

• law of independent assortment

• law of dominance

This term describes a genotype that contains two of the same allele

• dominant

• recessive

• homozygous

• heterozygous

This term describes a genotype that contains two different alleles

• dominant

• recessive

• homozygous

• heterozygous

This pattern of inheritance produces a heterozygote phenotype that is a blend of the two forms of a trait

• simple dominance

• incomplete dominance

• codominance

• polygenic inheritance

This pattern of inheritance produces a heterozygote phenotype in which both forms of the trait are expressed together

• simple dominance

• incomplete dominance

• codominance

• polygenic inheritance

This pattern of heredity is controlled by three or more different forms of a gene, and each produces a different phenotype

• simple dominance

• incomplete dominance

• codominance

• multiple alleles
