Crossing over ____.
A)generally results in binary fission
B)involves nucleoli
C)involves breakages and exchanges being made between sister chromatids
D)results in new combinations of alleles being channeled into the daughter cells
E)is the same as disjunction

Question

Quizplus · Accepted Answer

Crossing over is a process that occurs during meiosis where homologous chromosomes exchange segments of their genetic material. This results in new combinations of alleles being passed on to the daughter cells, increasing genetic diversity. It does not involve binary fission, nucleoli, exchanges between sister chromatids (it involves homologous chromosomes instead), or disjunction (which refers to the separation of chromosomes).
