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

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 drtusharchauhan

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 …

What is Missing Chromosome?

Chromosome / By drtusharchauhan

An error in meiosis causes a change in the number of chromosomes in which sometimes a chromosome got missing causing a variety of health problems. Those are also known as missing chromosome disorders, for example, Turner syndrome. Numerical chromosomal abnormalities are significantly involved in varieties of health conditions due to loss or gain of genetic …

What does it mean to have an Extra Chromosome?

Chromosome / By drtusharchauhan

“An extra chromosome in our genome means a person or fetus has one additional chromosome with a pair besides 23 pairs and causes serious health issues.” ‘Chromosome’ is a common term in recent times, we know, it is the unit of inheritance or a place where the DNA is located. Scientifically, a network of histone …

Are YY Chromosomes Possible?

Chromosome / By drtusharchauhan

Two Y chromosomes are present in a chromosomal abnormality known as XYY or Jacob’s syndrome, however, only YY chromosomes in a genome aren’t reported to date. X and Y chromosomes are two genetic material repositories significantly important for humans. The Y chromosome is present in males while the X chromosome is present in males and …
