which one is odd between zygotene, pachytene, diplotene, telophase with reason
Answers
Answer:
Telophase is odd because all three I.e zyogotene,pachytene and diplotene are the phases of pro phase in meiotic divisison 1 and Telophase is the last phase of meiosis.
Explanation:
Meiosis is divided into Meiosis I and meiosis ll
Meiosis I separates the pairs of homologous chromosomes.
Prophase I
The homologous chromosomes pair and exchange DNA to form recombinant chromosomes. Prophase I is divided into five phases:
Leptotene: chromosomes start to condense.
Zygotene: homologous chromosomes become closely associated (synapsis) to form pairs of chromosomes (bivalents) consisting of four chromatids (tetrads).
Pachytene: crossing over between pairs of homologous chromosomes to form chiasmata (sing. chiasma).
Diplotene: homologous chromosomes start to separate but remain attached by chiasmata.
Diakinesis: homologous chromosomes continue to separate, and chiasmata move to the ends of the chromosomes.
