Question

Quizplus · Accepted Answer

A chiasma is a point where non-sister chromatids of homologous chromosomes cross over and exchange genetic material during meiosis. Therefore, the correct answer is A) homologous or nonsister chromatids. B) sister chromatids are identical copies of each other, so they cannot exchange genetic material at a chiasma. C) nonhomologous chromosomes do not pair up during meiosis, so they cannot form a chiasma. D) daughter cells are the result of cell division and are not involved in the formation of a chiasma.
