WebDrag "True" or "False" to the end of each statement. Since independent assortment can occur in different ways during meiosis, two people could come up with different color-combinations of chromosomes in their drawings of gametes, and both be correct. False. In this model, the color codes emphasize that two homologous chromosomes contain the ... WebAfter crossing over, the spindle begins to capture chromosomes and move them towards the center of the cell (metaphase plate). This may seem familiar from mitosis, but there is a twist. Each chromosome attaches to microtubules from just one pole of the spindle, and the two homologues of a pair bind to microtubules from opposite poles.

WebWhat is crossing over? The point where sister chromatids attach during meiosis. What is the centromeres? The phase of meiosis where the centrosomes use the mitotic spindles to align the sister chromatids along the center of the cell. What is the metaphase? WebCrossing over is a process that happens between homologous chromosomes in order to increase genetic diversity. During crossing over, part of one chromosome is exchanged with another. The result is a hybrid chromosome with a unique pattern of genetic material. factory reset fanvil x5u
