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 the chromosome is lost or removed.

Front

What is duplication in chromosomal mutations?

Back

Duplication is a chromosomal mutation where a segment of the chromosome is copied and remains within the chromosome.

Front

What is inversion in chromosomal mutations?

Back

Inversion is a chromosomal mutation where a segment of the chromosome detaches, flips 180 degrees, and reattaches.

Front

What is translocation in chromosomal mutations?

Back

Translocation is a chromosomal mutation where a segment of one chromosome detaches and reattaches to a different chromosome.

Front

What are the potential effects of chromosomal mutations?

Back

Chromosomal mutations can lead to genetic disorders, developmental issues, or cancer.

Front

How can chromosomal mutations occur?

Back

Chromosomal mutations can occur due to errors during cell division, exposure to radiation, or certain chemicals.

Front

What is the difference between structural and numerical chromosomal mutations?

Back

Structural mutations involve changes in the structure of chromosomes (like deletion, duplication, inversion, translocation), while numerical mutations involve changes in the number of chromosomes (like aneuploidy).

Front

What is aneuploidy?

Back

Aneuploidy is a condition where the number of chromosomes is not an exact multiple of the haploid number, often resulting in genetic disorders.

Front

What is a karyotype?

Back

A karyotype is a visual representation of an individual's chromosomes, used to identify chromosomal abnormalities.
