If chiasmata are observed to be moving towards the ends of chromosomes during meiosis, which sub-stage of Prophase I is most likely occurring?

When number of chromosomes is already reduced to half in the first reductional division of meiosis, what is the necessity of second meiotic division?

A bivalent

The stage during which separation of the paired homologous chromosomes begins is?

Crossing over occurs in

Select the event of cell cycle which shows the importance of synapsis and the formation of chiasmata

Which of the following statement(s) is/are not correct about meiosis?

I. Meiosis involves pairing of homologous chromosomes and recombination between them

II. Two diploid cells are formed at the end of meiosis-II

III. Meiosis involves two sequential cycles of nuclear and cell division called meiosis-I and meiosis-II, but only a single cycle of DNA replication

IV. Meiosis-I is initiated after the parental chromosome replication which produce identical sister chromatids at the S-phase

The correct option is

Which of the following is unique to mitosis and not a part of meiosis?

Dissolution of synaptonemal complex occurs in

In which of the following stages of the cell cycle chromosome number becomes half?

During meiosis, the alleles of the parental pair separate or segregated from each other. How many allele(s) is/are then transmitted to a gamete?
