Define a monohybrid cross.

Back

A genetic cross between parents that differ in one trait.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup, while phenotype refers to the observable traits.

Front

What does it mean for an allele to be dominant?

Back

A dominant allele is one that expresses its trait even in the presence of a recessive allele.

Front

What is a Punnett square used for?

Back

A Punnett square is used to predict the genotypes and phenotypes of offspring from a genetic cross.
