Which of the following processes occurs when homologous chromosomes cross over?Group of answer choicesCorresponding segments of sister chromatids are exchanged.Two sister chromatids exchange identical pieces of DNA.Two sister chromatids get tangled, resulting in one re-sequencing its DNA.Maternal alleles are “corrected” to be like paternal alleles and vice versa.Corresponding segments of nonsister chromatids are exchanged.Next
