Phenotype vs Genotype

Front

What is the definition of genotype?

Back

The genotype is the genetic makeup of an organism, represented by the alleles it possesses (e.g., AA, Aa, aa).

Front

What is the definition of phenotype?

Back

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

Front

What does homozygous mean?

Back

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

Front

What does heterozygous mean?

Back

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

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 'RR'.

Front

What is an example of a heterozygous genotype?

Back

An example of a heterozygous genotype is 'Rr'.

Front

If red color is dominant in flowers, what is the phenotype of a flower with genotype 'RR'?

Back

The phenotype of a flower with genotype 'RR' would be red.

Front

If a flower has the genotype 'Rr', what is its phenotype if red is dominant?

Back

The phenotype of a flower with genotype 'Rr' would also be red.

Front

What is the relationship between genotype and phenotype?

Back

The genotype determines the phenotype, but the phenotype can also be influenced by environmental factors.
