2024 Genotype vs Phenotype

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism (the alleles it carries), while phenotype is the observable physical or biochemical characteristics of that organism, determined by both genotype and environment.

What does it mean if a trait is dominant?

Back

A dominant trait is one that will appear in the phenotype even if only one copy of the allele is present (e.g., Pp or PP).

Front

What does it mean if a trait is recessive?

Back

A recessive trait is one that will only appear in the phenotype if two copies of the allele are present (e.g., pp).

Front

If a plant has the genotype Pp, what color flowers will it have?

Back

Purple flowers, because purple (P) is dominant over white (p).

Front

What are the possible genotypes for a trait that is dominant (E) and recessive (e)?

Back

The possible genotypes are EE (homozygous dominant), Ee (heterozygous), and ee (homozygous recessive).

Front

What phenotype is represented by the genotype ee?

Back

Smooth chin, because ee is the only genotype that expresses the recessive trait.

What phenotype is represented by the genotype HH?

Back

Hair on fingers, because HH is homozygous dominant for the hair trait.

How much genetic material do you inherit from each parent?

Back

You inherit 50% of your DNA from your mom and 50% from your dad.

What is a homozygous genotype?

Back

A homozygous genotype has two identical alleles for a particular gene (e.g., AA or aa).

What is a heterozygous genotype?

Back

A heterozygous genotype has two different alleles for a particular gene (e.g., Aa).
