Different forms of a single gene.

• Genotype

• Chromosome

• Trait

• Allele

When 2 different dominant traits are inherited and they are both expressed.

• Incomplete Dominance

• Co-Dominance

• Recessive

• Punnett Square

Segments of DNA that carry hereditary information and are passed from parent to offspring.

• Chromosomes

• Probability

• Ressesive

• Genes

The gene combination that is present in a cell or organism for a particular trait.

• Phenptype

• Hybrid

• Pure

• Genotype

An organism or cell in which the pair of genes for a particular trait are different.

• Hybrid

• Heredity
