Homologous pairs of chromosomes are lined up independently of other such pairs during _____.
metaphase
A) telophase
B) metaphase
C) prophase
D) anaphase

Respuesta :

Answer: it happens during Prohase1 and Metaphase 1.

Explanation:

It is during Prophase 1 and metaphase that genetic recombination occurs. The homologues pairs of chromosomes or tetrads are first lined up against each other. In this phase crossing over occurs at the charismata. This is the events that occur between neighbouring tetrads which swap genetic information with each other.
