A process in which a sister chromatid inherited from the mother and a sister chromatid inherited from the father pair up and form tetrads and exchange DNA to form genetically diverse gametes is called ________.
A) cell cycle
B) prophase
C) cytokinesis
D) crossing over

Question

Quizplus · Accepted Answer

Crossing over is the process in which homologous chromosomes pair up and exchange DNA during meiosis I. This results in genetically diverse gametes, as the chromosomes shuffled and new combinations of alleles are formed. The cell cycle refers to the sequence of events that a cell goes through as it grows and divides. Prophase is a stage of mitosis or meiosis when the chromosomes condense and become visible. Cytokinesis is the final stage of cell division, when the cytoplasm is divided into two daughter cells. None of these processes involve the exchange of genetic material between homologous chromosomes.
