Heredity review

The Alleles that a person has in there genes- you cannot see(think of how we cannot actually see someone's DNA)
EX: Aa, aa, AA

Genotype

Physical Appearance- what you can see/describe about someone
Ex: red hair, brown eyes, curly hair

Phenotype

• Genotype

• phenotype

alleles are represented by uppercase letters
- always overpowers the recessive and shown in phenotype

Dominant

alleles are represented by lowercase letters

- always overpowered if the dominant allele is present or 'hidden' if the phenotype

recessive

vocab

Multiple Choice

The form of an inherited trait that masks (covers up) the other form of the same trait.

• 
  hybrid trait

• 
  dominant trait

• recessive trait

Multiple Choice

If I had the alleles : Aa.... would the dominant or recessive trait be shown?

• Dominant

• recessive

• both

Multiple Choice

in the genotype: aa .... which trait would be displayed?

• recessive

two different alleles
Ex: Aa

heterozygous

Same alleles

Ex: AA or aa

AA= homozygous dominant
aa= homozygous recessive
