Homologoes Chromosomes Pair Form Tetrad Held Points Called

Synapsis in Prophase I involves homologous chromosomes pairing to form tetrads held together by chiasmata, which are sites of genetic material crossover between non-sister chromatids, leading to recombination.

La sinapsis en la Profase I implica el apareamiento de cromosomas homólogos en tétradas, mantenidas por quiasmas, que son sitios de entrecruzamiento de material genético entre cromátidas no hermanas, resultando en recombinación.

Original
homologoes chromosomes pair up to form a tetrad
are held together at points called chiasmata (singular: chiasma)
this is site of genetic material crossover between non-sister chromatids --> recombination with new genes
