Phenotype vs. Genotype & Homozygous vs. Heterozygous

Front

What is a genotype?

Back

A genotype is the genetic makeup of an organism, represented by the alleles it possesses (e.g., GG, Gg, gg).

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by its genotype and environment (e.g., flower color, fur texture).

Front

What does homozygous mean?

Back

Homozygous refers to having two identical alleles for a particular gene (e.g., GG or gg).

Front

What does heterozygous mean?

Back

Heterozygous refers to having two different alleles for a particular gene (e.g., Gg).

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic composition, while phenotype refers to the physical expression of that genotype.

Front

What is an example of a homozygous recessive genotype?

Back

An example of a homozygous recessive genotype is 'gg'.

Front

What is an example of a homozygous dominant genotype?

Back

An example of a homozygous dominant genotype is 'GG'.

Front

What is an example of a heterozygous genotype?

Back

An example of a heterozygous genotype is 'Gg'.

Front

How does a phenotype relate to the environment?

Back

A phenotype can be influenced by environmental factors, such as temperature, light, and nutrition, in addition to genetic factors.

Front

What is an example of a phenotype in animals?

Back

An example of a phenotype in animals is the color of a dog's fur.
