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

12/10/2021

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, […]

Chromosome 2: Genes, Abnormalities and Disorders

10/16/2021

Chromosome number 2 is among the 23 pairs of the human chromosome, a submetacentric chromosome with a length of 242, 193,529 bp in length having approximately 1767 coding genes. Present in a pair, the present set of chromosomes possesses a total of 8% of genomic DNA having 242 million bp DNA sequences on it. The

Importance of Metaphase Chromosomes in Karyotyping

08/28/2021

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

04/30/2021

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

Common Clinical Karyotyping FAQs

04/29/2021

Karyotyping is a common clinical genetic technique to observe and investigate chromosomes. Scientists using the technique for a long time, though not less known. The karyotyping technique is now common for prenatal testing, fetal chromosome testing and to rule out other pregnancy-related problems and chromosomal aberrations. It is very important for couples who are going

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

04/29/2021

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 Disorders are caused by the Double Monosomy?

04/27/2021

Double monosomy is the aberrant chromosomal condition commonly found in the plant genome but so rare in the human genome. Chromosomal aberrations or defects we can say, are classified broadly into aneuploidies. The monosomy is a kind of aneuploidy in which a single chromosome from a pair is missing. Meaning, that instead of normal 46

What is Ring Chromosome?- Definition, Mechanism and Abnormalities

04/27/2021

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

Importance of Karyotyping in Infertility Screening

04/26/2021

Karyotying is a technique to find chromosomal abnormalities such as Flinefeture, syndrome, Y chromosome microdeletions, Turner syndrome, sex reversal and other translocations in male and female infertility. Do You know? 15% of the world population suffer from infertility. 1 in 6 couples faces difficulties to reproduce. Karyotype abnormalities are reported in 2 to 14% of
