Phenotype vs Genotype

Front

What is a phenotype?

Back

The phenotype is the observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What is a genotype?

Back

The genotype is the genetic constitution of an individual, representing the specific alleles inherited from the parents.

Front

What does homozygous mean?

Back

Homozygous refers to having two identical alleles for a particular gene, such as TT or rr.

Front

What does heterozygous mean?

Back

Heterozygous refers to having two different alleles for a particular gene, such as Rr.

Front

What is an example of a phenotype?

Back

A flower's red color is an example of a phenotype.

Front

What is an example of a genotype?

Back

The genotype RR represents a homozygous dominant flower.

Front

If a flower has the genotype Rr, what is its phenotype?

Back

The phenotype would be red if red is the dominant color.

Front

What is the relationship between genotype and phenotype?

Back

The genotype determines the potential phenotype, but environmental factors can also influence the phenotype.

Front

What is a dominant allele?

Back

A dominant allele is an allele that expresses its trait even when only one copy is present in the genotype.

Front

What is a recessive allele?

Back

A recessive allele is an allele that only expresses its trait when two copies are present in the genotype.
