Which one of the following pairs is correctly matched?

Options

  1. AAnaphase I - Homologous chromosomes are separated
  2. BMetaphase I - Pairing of maternal and paternal homologous chromosomes takes place
  3. CInterphase - A nuclear envelope encloses each haploid set of chromosomes
  4. DProphase I - Non-homologous chromosomes are separated

Correct answer

A. Anaphase I - Homologous chromosomes are separated

Step-by-step solution

Anaphase I involves separartion of homologous chromosomes which start moving opposite poles so each tetrad is divided into two daughter dyads. In Metaphase I Centromeres of homologous chromosomes lie equisdistant from equator and are directed towards the poles while arms generally lie horizontally on the equator. Each homologous chromosome has two kinetochores and both the kinetochores of a chromosome are joined to the chromosomal or tractile fibre of same side. Whereas Prophase I is divided in five subphases i.e.,
