Chromosomal Mutations

Front

What is a chromosomal mutation?

Back

A chromosomal mutation is a change in the structure or number of chromosomes, which can affect genetic information.

Front

Define duplication in the context of chromosomal mutations.

Back

Duplication is a type of chromosomal mutation where a segment of a chromosome is copied, resulting in two copies of that segment.

Front

What is inversion in chromosomal mutations?

Back

Inversion is a mutation where a segment of a chromosome breaks off, flips around, and reattaches, altering the gene order.

Front

What does deletion mean in terms of chromosomal mutations?

Back

Deletion refers to a mutation where a segment of a chromosome is lost or breaks off.

Front

What is translocation in chromosomal mutations?

Back

Translocation is a mutation where a segment of a chromosome breaks off and attaches to a non-homologous chromosome.

Front

How can you identify a deletion mutation?

Back

A deletion mutation can be identified if a chromosome is shorter than its homologous match.

Front

What are the potential effects of chromosomal mutations on an organism?

Back

Chromosomal mutations can lead to genetic disorders, developmental issues, or cancer, depending on the genes affected.

Front

What is the significance of chromosomal mutations in evolution?

Back

Chromosomal mutations can introduce genetic diversity, which is essential for evolution and adaptation.

Front

Explain how chromosomal mutations can occur during meiosis.

Back

Chromosomal mutations can occur during meiosis due to errors in chromosome segregation or recombination.

Front

What is the difference between a chromosomal mutation and a point mutation?

Back

A chromosomal mutation involves changes in chromosome structure or number, while a point mutation is a change in a single nucleotide.
