Chromosomes were first discovered by the scientist Walter Flemming in the late 19th century. Flemming observed and described the thread-like structures in the nucleus of cells, which we now know to be chromosomes.

In which animal polytene chromosome was discovered?
The polytene chromosome was first discovered in the salivary glands of the larvae of fruit flies (Drosophila melanogaster). These chromosomes have characteristic banding patterns due to repeated DNA strands that have replicated side by side.
Short sex chromosome discovered in fruit flies?
The short sex chromosome in fruit flies, known as the Y chromosome, carries genes related to male traits and fertility. It determines the sex of the offspring when paired with an X chromosome. In evolutionary terms, the Y chromosome has undergone significant degeneration, leading to a size reduction and loss of genetic material compared to the X chromosome.
What is the female chromosome?
The X chromosome is one of the two sex-determiningchromosomes in many animal species, including mammals (the other is the Y chromosome). It is a part of the XY sex-determination system and X0 sex-determination system. The X chromosome was named for its unique properties by early researchers, and this resulted in its counterpart being named the Y chromosome for the next letter in the alphabet when it was discovered later.
Who discovered the Xist gene?
The Xist gene was discovered by Catherine D. Ballabio and Alan P. Wolffe in 1991. They identified it as a key player in X-chromosome inactivation in female mammals.
What is the designation for the short arm of a chromosome?
The short arm of a chromosome is denoted as "p" in chromosome nomenclature. For example, if a chromosome is labeled as 15p, it means that it is chromosome 15 with the short arm indicated.
Who discovered the x chromosome?
Hermann Henking
Who discovered chromosome as a heredity bearer?
Gregor Mendel

How did the chromosome get its name?
When th chromosome was discovered, it was given that name for a reason. Translated from Greek to German, it was khromasoma. When translated to English, it means color body.

How was cri du chat discovered?
It's very rare it happens when chromosome #5 is out of place and goes missing.
Who discovered xyy syndrome?
XYY syndrome was first discovered by Dr. Avery Sandberg and co-workers in 1961. They identified the presence of an extra Y chromosome in males.
What genetic research has been done on Alzheimer's disease?
Potentially the most important genetic link was discovered in the early 1990s on chromosome 19. A gene on this chromosome, called apoE, codes for a protein involved in transporting lipids into neurons.
Who discovered the Xist gene?
The Xist gene was discovered by Catherine D. Ballabio and Alan P. Wolffe in 1991. They identified it as a key player in X-chromosome inactivation in female mammals.
When was achondroplasia discovered?
In 1994 Dr. John Wasmuth and his colleagues discovered that a mutation of the fibroblast growth factor receptor-3 (FGFR3) gene on human chromosome 4 causes achondroplasia.
