Question

Lampbrush chromosomes occur inside

• A. Nucleus of human cells
• B. Ocytes of Frog/amphibian
• C. Salivary glands of drosophila
• D. Salivary glands of silk moth

Answer 1

The correct option is B Ocytes of Frog/amphibian

• Lampbrush chromosomes are also called diplotene chromosomes because they are formed during the diplotene stage of prophase1 of meiosis cell division due to the active transcription of many genes.
  
• These chromosomes are seen during the early prophase stage and are bivalent having two conjugating homologues joined at chiasmata.
• They are a special type of chromosome found in the developing oocytes of most animals (except mammals).
• So, the correct answer is 'Oocytes of Frog/amphibian'.
