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 terms of chromosomal mutation?

Back

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

Front

What is duplication in terms of chromosomal mutation?

Back

Duplication is a chromosomal mutation where a segment of DNA is copied, resulting in multiple copies of that segment.

Front

What is inversion in terms of chromosomal mutation?

Back

Inversion is a chromosomal mutation where a segment of DNA is reversed end to end.

Front

What is translocation in terms of chromosomal mutation?

Back

Translocation is a chromosomal mutation where a piece of chromosome breaks off and attaches to another chromosome.

Front

What is a gene?

Back

What is trisomy?

Back

Trisomy is a genetic condition where an individual has three copies of a chromosome instead of the usual two.

Front

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

Back

A mutation refers to any change in the DNA sequence, while a chromosomal mutation specifically involves changes in the structure or number of chromosomes.
