Complex Inheritance & Human Heredity

Incomplete dominance means that there traits are...

• expressed equally

• dominant

• recessive

• blended

What pattern of inheritance is shown in this image?

• Codominance

• Incomplete dominance

• Complete dominance

Snap dragon color is a incomplete dominant trait. A red flower (RR) is crossed with white flower (R'R')? What color are flowers that are RR'? Think of the playdoh example we discussed

• Red

• Red and White

• White

• Pink

NGSS.HS-LS3-2

Diagrammed family history that is used to study inheritance patterns of a trait through several generations and that can be used to predict disorders in future offspring.

• Pedigree

• Carrier

• Autosome

• Karyotype

Having more than two alleles for the same trait

• Telomere

• Autosome

• Epitasis

• Multiple Alleles

Individual heterozygous for recessive disorder such as cystic fibrosis or Tay - Sachs disease (so the person does NOT have it but can pass down to their offspring)

• Pedigree

• Carrier

• Autosome

• Telomere
