Punnett Square Vocabulary Flashcard

Front

What does the term 'dominant' mean in genetics?

Back

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

Front

What does the term 'recessive' mean in genetics?

Back

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

Front

What is the ratio of phenotypes in a monohybrid cross?

Back

In a typical monohybrid cross, the phenotypic ratio is often 3:1 for dominant to recessive traits.
