what is a genotype
The genetic makeup of an organism
How many generations?
3 generations
What is the dominant trait
The trait represented by a capital letter
what is a recessive trait
The trait represented by a lowercase letter
What is the allele

which eye color is dominant?
Brown eyes
A. Color blindness
B. Tay-sachs disease
C. Cystic fibrosis
D. Sickle cell anemia
A. Color blindness
Type A=
Type B=
Type AB=

BB, BO
Codominant
OO, Recessive
How do you classify the following genotype: AA
Homozygous Dominant
Example of a dominant/recessive phenotype pattern
A. A pea plant needs to inherit two copies of the allele for wrinkled seeds to produce that phenotype
B. A pea plant inherits one allele for smooth seeds and produces smooth seeds
C. Two alleles are expressed evenly to create a spotted phenotype in cow coat color
D. A person needs to inherit multiple alleles in a pathway to produce a protein
B. A pea plant inherits one allele for smooth seeds and produces smooth seeds
What is 3:1?
The ratio of dominant to recessive offspring that Mendel always found in the second generation of his experiments
Why are recessive traits less common in females than in males?
females have two X chromosomes
What characteristics are controlled by multiple alleles?
Hair color
Hair texture
Eye color
Physical structure
