NGSS.HS-LS3-2

One variant of a gene that does not produce a trait if it is masked by a the other variant

• homozygous

• heterozygous

• dominant

• recessive

A particular variant of a gene, which expresses itself more strongly so that the trait it codes for is seen.

• dominant

• recessive

• heterozygous

• homozygous

Having a single set of unpaired chromosomes.

• genotype

• phenotype

• diploid

• haploid

The genetic makeup of an organism; often we use alleles to represent the variant forms of the genes.

• codominance

• incomplete dominance

• genotype

• phenotype

NGSS.HS-LS1-1

The observable physical or biochemical characteristics of an organism, as determined by both genetic makeup and environmental influences.

• genotype

• phenotype

• heterozygous

• homozygous

Different genes separate from one another when reproductive cells develop; this occurs randomly

• law of independent assortment

• law of segregation
