19. Mendelian Inheritance

Mendelian Inheritance describes how...

• Likely is is that a particular genetic event will occur

• Certain genes are controlled by 2 alleles

• Both alleles are the same

• Both alleles are different

A Punnett Square is...

• Diagram showing the gene combinations that might result from a genetic cross

• Likelihood that a particular genetic event will occur

• The genetic makeup that leads to the trait - the alleles

• The physical characteristic that is seen

An allele is

• The physical characteristic that is seen

• Likelihood that a particular genetic event will occur

• A version of a gene / different common forms of one particular gene
