A gene can exist in more than one form or allele.

• Organisms inherit two alleles for each trait.
• When sex cells are produced (by meiosis), allele pairs separate leaving each cellwith a single allele for each trait.
• When the two alleles of a pair are different, one is dominant and the other is recessive.

One of these principles, now called Mendel's law of segregation, states that allele pairs separate or segregate during gamete formation, and randomly unite at fertilization.

The phenotype is the physical expression, or characteristics, of that trait. For example, two organisms that have even the minutest difference in their genes are said to have different genotypes.
