Inheritance Practice

Look around the class, predict which phenotype is dominant.

Curly Hair

Straight Hair

• Curly

• Straight

Look at the genotype now: Which allele is dominant?

Curly Hair = C

Straight Hair = c

• Curly

• Straight

Look around the class, predict which phenotype is dominant.

Phenotype: Dark Hair vs Light Hair

• Dark

• Light

Look at the genotype now: Which allele is dominant?

Dark Hair = D

Light hair = d

• Dark

• Light

Look around the class, predict which phenotype is dominant.

Attached Earlobe

Detached Earlobe

• Attached Earlobe

• Detached Earlobe

Look at the genotype now: Which allele is dominant?

Attached Earlobe = e

Detached Earlobe = E

• Attached Earlobe

• Detached Earlobe

Look around the class, predict which phenotype is dominant.

Freckles

No Freckles

• Freckles

• No Freckles

Look at the genotype now: Which allele is dominant?

Freckles = f

No Freckles = F

• Freckles

• No Freckles

Look around the class, predict which phenotype is dominant.
