Identify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings. a) the diagram shows crossing over. crossing over increases the genetic variation of the gametes produced in meiosis, by allowing for different allele combinations than present in the parents. this results in greater diversity in the offspring produced. b) the diagram shows a chromosome mutation called translocation. translocation introduces new traits into the gene pool of the gamete by trading genes between nonhomologous chromosomes. this results in greater diversity in the offspring produced. c) the diagram shows crossing over. crossing over introduces new traits into the gene pool of the gamete by trading genes between homologous chromosomes. this results in the formation of more diverse gametes. d) the diagram shows a chromosome mutation called inversion. in inversion, a segment of a chromosome is reversed end to end. inversion rearranges the genes on a chromosome, providing more diverse gametes.
