Question

what happens in anaphase

Answer 1

Answer :-

Anaphase includes two parts -

Anaphase 1 :-

• "Anaphase 1" is the stage in which the homologous chromosomes get separated from each other.

• Each distinct pole receives either a maternal or a paternal chromosome.

• The process of separation of "Tetrads" into "Dyads", is known as "Disjunction".

• Disjunction during "Anaphase 1" results in the reduction of the chromosome number to half the original amount.

• In "Anaphase 1", the centromere undergoes no division.

• In "Anaphase 1", the poleward movement of "Dyads" takes place.

Anaphase 2 :-

• In "Anaphase 2", the centromeres get divided.

• In "Anaphase 2", the chromatids get separated.

• In "Anaphase 2", the chromatids begin to move towards the opposite poles.

• In "Anaphase 2", the spindle fibres pull the chromatids which leads to the movement of the chromatids towards the opposite poles.
