During meiosis, homologous chromosomes line up next to each other. If one arm of a chromatid crosses over the arm of another chromatid, what results? (SC.912.L.16.17)

Question

*
1 point
the creation of an additional sex cell
the independent assortment of genetic material
a possible change in the offspring cell’s functionality
additional variation in the DNA combination of each sex cell formed

Answer 1

During meiosis, when homologous chromosomes undergo crossing over, it results in additional variation in the DNA combination of each sex cell formed. This process allows for the exchange of genetic material between chromatids, leading to new combinations of genes that can be passed on to offspring. Therefore, the correct answer is:

additional variation in the DNA combination of each sex cell formed.
