Question

Which of the following is considered as drosophila of the plant kingdom?
A. Neurospora
B. Synchytrium
C. Peziza
D. Amanita

Answer 1

Hint:- Drosophila melanogaster considered as an ideal organism for genetic studies. Drosophila is very small in size and can be easily grown in laboratories. They have a very small life span.

Complete answer:
Let’s first know the importance of Drosophila.
Drosophila is considered as the Queen of genetics. Drosophila are small flies and without problems reared in the laboratory. They have a brief existence cycle. A brand new generation of person flies can be produced each week. In drosophila polytene chromosomes are found.
The genetic info (DNA) altogether cells are carried within the chromosomes (literally "coloured bodies") a fancy of deoxyribonucleic acid and specialised proteins (histones) packed in the cell's nucleus like humans, the chromosomes of Drosophila melanogaster come in however in contrast to humans, that have twenty three pairs of chromosomes, the two-winged insects has solely four: a try of sex chromosomes (two X chromosomes for females, one X and one Y for males).
The low, manageable variety of chromosomes was a key attraction of this organism in early genetic studies. Neurospora belongs to the kingdom fungi of the plant kingdom.
Due the following reasons it is considered as model organism:
- It is easily cultured under laboratory conditions.
- They reproduce fast as compared to other organisms and it is capable of surviving on minimal media.
Most of the characteristics of Neurospora are similar to drosophila. Hence Neurospora is called drosophila of plant genetics.
Hence the correct option is (A) Neurospora.

Note:-
- Polytene chromosome also known as salivary gland chromosome-These chromosomes are present in the salivary gland of insect of order diptera. It is due the presence of these chromosomes that maximum cytological studies have been made in Drosophila.
- Drosophila is known as Queen of genetics.
- Neurospora is known as Queen of plant genetics.
