STAAR Meiosis and Mitosis Review

Crossing over allows for a ton of variation, why is that?

• Pieces swap between homologous chromosomes and make everything stay the same

• Pieces swap between homologous chromosomes and make things unique

• Chromosomes move to one side and start to make things whole

• Chromosomes move to the other side of where they started which leaves a blank spot
