The lampbrush chromosomes occuring in prophase of meiosis II are highly elongated special kind of synapsed mid-prophase or diplotene chromosome bivalents which have already undergone crossing over. Lampbrush chromosomes occur in pairs. Each chromosome of a pair has a double main axis due to presence of two elongated chromatids. Both the adjacent chromatids bear rows of large number of chromomeres. Two adjacent chromomeres are separated by interchromomeric stretches. Many of the chromomeres give out lateral projections or loops. The lateral loops provide a test tube or lampbrush-like appearance to the chromosome pair. Lateral loops take part in rapid transcription of DNA to mRNA meant for synthesis of yolk and other substances required for growth and development of Meiocyte.

Lampbrush chromosomes are seen in which typical stage?a)Mitotic anapha...
Explanation:
Lampbrush chromosomes are a characteristic feature of meiotic prophase I in the oocytes of many animals, including amphibians, birds, and some fishes. These chromosomes are named for their appearance, which resembles the brushes used to clean laboratory glassware.
The chromosomes in the oocyte become highly extended and their chromatin fibers become loosely arranged, resulting in the formation of long, thin, and highly convoluted structures that resemble a lampbrush. These chromosomes extend from the nuclear envelope, with loops of chromatin projecting outward on either side of the central axis.
The structure of lampbrush chromosomes allows for the visualization of gene transcription and RNA processing in real-time. This makes them a valuable tool for studying gene expression and chromosome structure in the early development of many species.
In summary, Lampbrush chromosomes are seen in the typical stage of meiotic prophase I in the oocytes of many animals.
