Verified by Toppr

  • 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'.
