Something you can SEE about a person. Example: Hair color, eye color, height.

Bits of DNA on our chromosomes that control Traits.

Differences (variations) in a trait. Example: Eye color can be blue, brown, green, etc.

Austrian monk who discovered a lot about laws of inheritance by studying pea plants.

an allele that always appears when it is present. You only need one dominant allele for it to show.

an allele that is hidden by a dominant allele. You must have two recessive alleles for the trait to show.

(homo = same) Both alleles are the same. Example: BB, bb, CC, cc, etc.

(hetero = different) Both alleles are different. Can also be called "Hybrid". Example: Bb, Cc, Tt

The genes that an individual has for a certain trait.

The physical way that an individual looks because of their genotype.

A way to predict how likely a genotype and phenotype are for offspring to inherit.

When the alleles are neither dominant nor recessive, BOTH traits show up.

The alleles Blend (Mix) together and create something new.

A change in a gene or chromosome.

The process of producing an organism that is genetically identical to another organism.

A body cell copying itself into a new identical cell.
