Review What does incomplete dominance mean and give an example

Design an Experiment Design an experiment to determine whether the pink flowers of petunia plants result from incomplete dominance

Compare and Contrast What is the difference between incomplete dominance and codominance

CH 11 INTRODUCTION TO GENETICS11.3 Other Patterns of Inheritance

In most organisms, genetics is more complicated, because the majority of genes have more than two alleles

Many important traits are controlled by more than one gene.

Incomplete Dominance Heterozygous

phenotype is a blending or mixing of the homozygous phenotypes.

Codominance

Both alleles are visible Speckled fur/feathers.

Multiple Alleles Gene with more than

two alleles.

Polygenic Traits

Traits controlled by two or more genes Wide range of phenotypes Skin color.

Genes and the Environment

Genes provide a plan for development Environment plays a role in how the plan unfolds.

Western White Butterfly

Spring hatches have more wing pigments than summer hatches

To fly the body temperature needs to be 28–40°C.
