Is the Y chromosome really disappearing- let’s findout a scientific answer

Chromosome / By

A single copy of the Y chromosome, dosage-sensitive gene sets and lack of recombination event may result in a genetic degeneration timely on the Y chromosome, possibly going extinct in the future, researchers suggest.  Related article: Are YY Chromosomes Possible? The question on the existence of the Y chromosome parted scientific fraternity into separate opinions, …

Importance of Metaphase Chromosomes in Karyotyping

Chromosome, Karyotyping / By

Metaphase chromosomes are often known as metaphase plates or “meta’s” only in technical terms, have significant importance in genetic research, especially in cytogenetics and karyotyping studies.  Techniques like conventional karyotyping, FISH- fluorescence in situ hybridization and SKY highly rely on metaphases. And therefore good, well-separated and sharper metaphases have been the objective first achieved. Although …

Investigating a Karyotype of 3q29 Microdeletion Syndrome

Chromosome abnormality / By

The 3q29 deletion syndrome occurs by deletion of some portion from the q arm of chromosome 3 results in phenotypic alterations.  Chromosome 3 is the largest metacentric chromosome, comprises 200 million base pairs which represent 6.5% of total genomic content. Deletions are chromosome defects that occur when a part of a chromosome from either of …

What is a Dicentric Chromosome?- Definition, Cause, Consequences

Chromosome abnormality / By

The dicentric chromosome is a highly uncommon event that occurs in the genome which causes genomic instability and cancer.  We have written many articles on common chromosome aberrations or chromosomal abnormalities such as a change in number, deletion, duplication and translocation.  These are common, studied well and can be identified easily using the conventional karyotyping …

What is Ring Chromosome?- Definition, Mechanism and Abnormalities

Chromosome abnormality / By

A ring chromosome is formed when the ends of the same chromosome fuse together and make a ring-like structure. Chromosome ring formation is associated with certain health-related conditions.  Broad two categorize of chromosome aberrations or chromosome abnormalities are structural and numerical aberrations. When any event alters the structure of a chromosome greatly is referred to …
