In a bivalent, you should be able to see_____ sister chromatids.. A physical exchange of material between two homologus chromosomes is called______.. The visible evidence that exchange of genetic material has occuredis called a ___________.. . the answer choices are:. chiasma. two. one. eight four. bivalent. crossing over. synapsis. centromere. cytokinesis

Answer 1

Homologous types of chromosomes pair together to form a bivalent. They undergo synapsis which is the process of pairing. In each bivalent. there would be a total of two centromeres  and  four sister chromatids. crossing over is the term used for the  physical exchange of material between two homologous chromosomes. A chiasma is the visible evidence that exchange of genetic material occured.
