Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by its genotype.

Front

Back

A Punnett square is a diagram used to predict the genotypes of offspring from a cross between two parents.

What does it mean for a trait to be sex-linked?

Back

Sex-linked traits are associated with genes located on sex chromosomes, often affecting males and females differently.
