A) polar microtubules contract, pulling attached chromosomes toward the poles. B) chromosomes condense. C) microtubules assemble between centrioles. D) nuclear membrane breaks down.

WebCrossing over is a process that happens between homologous chromosomes in order to increase genetic diversity. During crossing over, part of one chromosome is exchanged with another.

Genetic recombination is a process that occurs during meiosis, which is the type of cell division that produces gametes. During this process, homologous chromosomes pair up and form a unit called a tetrad.
