NGSS.HS-LS3-2

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

• homozygous

• heterozygous

• allele

• hybrids

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

• incomplete dominance

• gentoype

• phenotype

• sex-linked gene

Trait produced by a combination of many alleles.

• polygenic inheritance

• dominant

• recessive

• sex-linked gene

Genetic makeup of an organism.

• phenotype

• genotype

• homozygous

• heterozygous

NGSS.HS-LS3-2

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

• homozygous

• heterozygous

• recessive

• dominant

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