What does the letter 'r' represent in the context of flower color in plants?

What is the total number of alleles a person carries for a trait?

Back

A person carries two alleles for each trait, one from each parent.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup (alleles) of an organism, while phenotype refers to the observable traits.

Front

If one brother has the genotype BB and the other has Bb, what can be said about their phenotypes?

Back

Both brothers have the same phenotype (brown eyes) but different genotypes.

What does a capital letter signify in genetics?
