What is translocation in genetics?

Back

A process where a piece of one chromosome detaches and reattaches to a different chromosome.

What is a chromosomal deletion?

Back

A mutation where a segment of the chromosome is lost.

Front

What is duplication in genetics?

Back

A mutation where a segment of the chromosome is copied, resulting in extra genetic material.

Front

Explain what a homologous pair of chromosomes is.
