What is a monohybrid cross?

Back

A genetic cross between individuals that differ in one trait, typically involving one pair of contrasting traits.

Front

What is a dihybrid cross?

Back

A genetic cross between individuals that differ in two traits, typically involving two pairs of contrasting traits.

Define mutation.

Back

A change in the DNA sequence that can lead to changes in phenotype.

Front

What is a substitution mutation?

Back

A mutation where one base pair in the DNA sequence is replaced by another.

Front

What is a deletion mutation?

Back

A mutation where one or more base pairs are removed from the DNA sequence.

Front

What is an insertion mutation?

Back

A mutation where one or more base pairs are added into the DNA sequence.

Front

What is a frameshift mutation?

Back

A mutation that shifts the reading frame of the genetic message, often caused by insertions or deletions.
