Sex Cells (Gametes)

Special cells that only have half the number of chromosomes

DNA

DeoxyriboNucleic Acid (DNA)

Genes

Sections of DNA that code for proteins that make our traits

Chromosomes

Squished up, coiled DNA

Protein

Molecules that turn DNA into cell parts/function

Passing of traits from parent to offspring

Alleles

Different forms of a gene

Dominant

The more powerful copy of a gene

Reccessive

The trait that is usually masked.

Homozygous

An organism has two of the same alleles (both dominant or both reccesive) for the same gene

Heterozygous

An organism has two different alleles (one dominant and reccesive) for the same gene

Phenotype

The physical or functional characteristics of an organism, produced by the interaction of genotype and environment during growth and development.

Genotype

The two copies of a gene (two alleles) for a trait
