Question

Lampbrush chromosomes are also called diplotene chromosomes because they

• A. Show chiasmata
• B. Resemble diplotene chromosomes
• C. Are in permanent diplotene stage
• D. All of the above

Answer 1

Answer: (D)

All of the above

• 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 'All of the above'.
