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

What is deletion in chromosomal mutations?

Back

Deletion is a type of chromosomal mutation where a segment of a chromosome is lost or removed.

Front

What is inversion in chromosomal mutations?

Back

Inversion is a type of chromosomal mutation where a segment of a chromosome breaks off, flips, and reattaches in the reverse orientation.

Front

What is duplication in 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 translocation in chromosomal mutations?

Back

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

Front

What is nondisjunction?

Back

Nondisjunction is a chromosomal mutation that occurs when chromosomes fail to separate evenly during meiosis, leading to gametes with an abnormal number of chromosomes.

Front

What are the effects of chromosomal mutations?

Back

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

Front

How can chromosomal mutations be detected?

Back

Chromosomal mutations can be detected through karyotyping, genetic testing, and molecular analysis.

Front

What is an example of a disorder caused by nondisjunction?

Back

Down syndrome is an example of a disorder caused by nondisjunction, resulting in an extra copy of chromosome 21.

Front

What is the significance of chromosomal mutations in evolution?

Back

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