Visual examples of genetics at work.

• F2 ears of varying phenotypes
• Individually wrapped

Dried and shrink-wrapped ears of corn illustrate naturally occurring Phenotype Ratios of genetic crosses.

3:1 Purple: Yellow: an F2 ear resulting in a P1 having the genotypes R/R and r/r.
3:1 Purple: White: an F2 result of a cross between parental Purple and White. A Single hybrid character with Dominance and Segregation.
9:3:3:1 Purple: White: Smooth: Sweet: an F2 from a parental Purple: Smooth: White: Sweet. Illustrates segregation of two characters.
