Metaphase I

Q. Metaphase I:

1. one version of each chromosome moves to a pole of the cell.
2. chromosomes gather at the two poles of the cell.
3. crossing over occurs.
4. chromosomes align on the central plane.

Q. Which one of the following pairs is correctly matched?

1. Anaphase I - Homologous chromosomes are separated
2. Interphase - A nuclear envelope encloses each haploid set of chromosomes
3. Metaphase I - Pairing of maternal and paternal homologous chromosomes take place
4. Prophase I - Non-homologous chromosomes are separated

Q. In Metaphase I, the centromeres
