Which of the following is NOT true about crossing over? it happens only in mitosis it happens during Prophase I it allows for genetic variability all of the above are true

Q6.5. Which statement below is TRUE? Crossing over shuffles genes between non-homologous chromosomes. During meiosis, cells arrange their alleles so that beneficial alleles are passed on together. Without crossing over, offspring would be genetically identical to parents. New combinations of alleles arise from the random events of crossing over, independent assortment, and mutation. Q6.6. What statement below is TRUE of the spindle during mitosis and meiosis? The spindle always separates sister chromatids during anaphase. The spindle always separates homologous chromosomes during anaphase. Chromosomes are always attached to both spindle poles during metaphase. The spindle always attaches to chromosomes at the kinetochore.
