Hello!
I believe the correct answer to your question would be sister chromatids.

They both describe each other so it would make some sense that they would name the color after it ♀️
Crossing over<span> occurs </span>between<span> prophase 1 and metaphase 1 and is the process where </span>homologous chromosomes<span> pair up with each other and </span>exchange<span> different segments of their genetic material to form recombinant </span>chromosomes<span>. It can also happen </span>during<span> mitotic division, which may </span>result<span> in loss of heterozygosity. </span>
B. cellular respiration, Hope this helps!
