A version of a gene.

When the heterozygous genotype results in a phenotype where both alleles are fully and separately expressed.

Chromosomes 1-44 in a human.

Only expressed in the homozygous state.

Genes travel on the X chromosome.

Chromosomes line up randomly during metaphase therefore it is possible for any combination of chromosomes to be passed on from parent to offspring.

A diagram that shows homologous chromosome pairs.

The macromolecule that runs your body and expresses your traits.

A genotype resulting from the inheritance of two different alleles from your parents.

Section of a chromosome that codes for a single protein.

Genes that are likely inherited together due to their physical proximity (closeness).

Overshadows the other allele in the heterozygous state.

The physical trait expressed

More than 2 versions of a gene (More than just "dominant" or "recessive".)

Condensed genetic material

When one gene overshadows another.

At the end of meiosis, each gamete formed should only have 1 copy from each homologous chromosome pair.

A genotype resulting from the inheritance of the same alleles from your parents.

The macromolecule that has the instructions for making you who you are

When the heterozygous genotype results in a phenotype where two alleles are blended together.

The actual alleles you inherit

The chromosomes that determine your sex

A person that has the gene for a trait or disease but doesn't show it.

Some versions of a gene are dominant over others.
