Biology Genetics and Heredity

The offspring of many generations that have the SAME traits.

• Purebred

• Hybrid

• Dominant allele

• Recessive allele

A chart that shows all the possible combinations of alleles that can result from a genetic cross.

• Probability

• Durick Square

• Punnett Square

• T-Chart

A unit that determines traits:
