Assume that an organism exists in which crossing over does not occur, but that all other processes associated with meiosis occur
normally. Consider how the absence of crossing over would affect the outcome of meiosis. Which of the following statements about meiosis would be true if crossing over did not occur? a. The daughter cells of meiosis I would be diploid, but the daughter cells of meiosis II would be haploid.
b. The two sister chromatids of each replicated chromosome would no longer be identical.
c. The four daughter cells produced in meiosis II would all be different.
d. The two daughter cells produced in meiosis I would be identical.
e. There would be less genetic variation among gametes.
f. Independent assortment of chromosomes would not occur.

Tight or occluding junctions This type of junction is also called zonula occludens and is the most apical structure in the epithelial cell. Zonula occludens describes, that there is a formed band of tight junctions which encircles every cell.
