Goal 2: Incomplete & CoDominance


Goal 2 incomplete codominance

I. Incomplete dominance- both alleles are expressed for a trait

  • the alleles mix together to blend the trait


Goal 2 incomplete codominance

A. Examples:

1. Red flower x White flower= Pink flower

RED=

WHITE=

PINK=

F1 Pheno:

F1 Geno:

Goal 2 incomplete codominance

II. Codominance -both alleles

are expressed and are shown

(not blended, but actually shown)

A. Example: Horses or cattle with both brown and white hairs

B= Brown hair W= White hair


Goal 2 incomplete codominance

B. Example: Orange and white fish are codominant.
