Chromosomal inversion is a type of a large-scale mutation. Mutation is a change in the nucleotide sequence of a gene or a chromosome.It is a large-scale type of mutation since it involves several nucleotides of a gene within a large chromosomal region.. Chromosomal inversions are a rearrangement within the chromosome.They result from a double break in a segment of the chromosome, with end for ...

Chromosomal inversions are a rearrangement within the chromosome and are of two types: pericentric (i.e. chromosomal inversions including the centromere) and paracentric (i.e. inversions that do not include the centromere). In zoology, inversion pertains to the switching from one sex to the opposite in certain animal species. Sexual inversion ...

en.wikipedia.org/wiki/Chromosomal_inversion

An inversion is a chromosome rearrangement in which a segment of a chromosome is reversed end to end. An inversion occurs when a single chromosome undergoes breakage and rearrangement within itself. Inversions are of two types: paracentric and pericentric. Paracentric inversions do not include the centromere and both breaks occur in one arm of the chromosome.

en.wikipedia.org/wiki/Deletion_(genetics)

In genetics, a deletion (also called gene deletion, deficiency, or deletion mutation) (sign: Δ) is a mutation (a genetic aberration) in which a part of a chromosome or a sequence of DNA is lost during DNA replication. Any number of nucleotides can be deleted, from a single base to an entire piece of chromosome. The smallest single base deletion mutations are believed to occur by a single base ...

Inversion in biology is the breaking of a chromosome in two places and the subsequent reordering re-insertion of the chromosome DNA. Inversions are divided into pericentric and paracentric types based on whether the centromere was involved. Inversions usually induce small chromosomal inversions.

fetal cells obtained by amniocentesis or lymphocytes from a blood sample can be cultured in the laboratory until they divide. Cell division is arrested in mid-metaphase by the drug Colcemid, a derivative of colchicine. The chromosomes can be stained by one of several techniques that produce a distinct pattern of light and dark bands along the chromosomes, and each chromosome can be recognized ...

What Is the Definition of Translocation Mutation? Translocation mutations take place when a portion of a chromosome is relocated. The genes from one chromosome can move to another position on the same chromosome; alternatively, they can become incorporated into a different chromosome.

ADVERTISEMENTS: In this article we will learn about:- 1. Origin of Inversions 2. Types of Inversion 3. Effects 4. Uses. Origin of Inversions: Inversion was first discovered by Sturtevant in 1921 in Drosophila. Later it was detected in a wide variety of plant and animal species. Inversions occur spontaneously, and can be induced artificially. In […]
