Genotype and Phenotypes
→ Your physical appearance does not always tell you the traits you can pass
down to your future children
→ There needs to be a way for us to describe the difference between
appearance and genetic
Phenotypes: The physical description of your traits
Ex. earlobes and tongue rollers
Genotypes: Describes what traits you have
These traits trait are called alleles
Alleles can be dominant or recessive
The dominant trait trait is always expressed
The recessive trait can be hidden
Example: the ability to roll your tongue is a dominant trait. Mary is unable to roll her
tongue
A) What is Mary’s phenotype?
- Mary cannot roll her tongue
B) What is Mary’s genotype?
E- can roll tongue
e- can’t roll tongue
Genotype: ee
