Incomplete Dominance~Sickle Cell Anemia

1. Incomplete Dominance is when one allele is not completely dominant over another.

2. The heterozygous phenotype is a blending of the two homozygous phenotypes.

3. This means the phenotype will be a mix of the traits.

4. The offspring of two heterozygous phentotypes can result in a 1AA:2Aa:1aa.  This means that the offspring could possibly have the trait of the grandparents rather than the parents.

5. This genetic type is expressed in animals, plants, and people.

Sickle Cell Anemia: A disease where your red blood cells form a crescent shape instead of the normal disk shape.

Sickle Cell Anemia is heterozygous in an offspring when one parent does not have the trait and another does. The offspring will then have some regular red blood cells and some crescent shaped because the disease is not recessive or dominant over the regular blood cells.
