an observable characteristic

A segment of DNA that codes for a trait

Why do children look like a combination of their parents?

Genetic traits are determined by one or more

A version or variation of a gene

When an organism has two of the same alleles, it is called

The observable expression of a trait

When an organism has two different alleles, it is called

The alleles that an organism has

This type of allele is expressed whether there are one or two copies present.

These types of alleles are only expressed if the organism has two copies
