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.

Which of the following scenarios is an example of the bottleneck effect? answers a in south africa, much of the afrikaner population is descended from a small number of dutch colonists. in this population, this is an unusually high frequency of pseudoxanthoma elasticum (pxe), an elastic tissue disorder. b four white-tailed deer are introduced to a park in finland. thirty years after their introduction scientists compare the genes in the population and find that there is no variation. c during the industrial revolution, london's air became filled with soot. as a result, birds started eating more of the lighter moths because they were easier to spot than their darker counterparts. over time, the moth population changed so that there were more darker moths than lighter ones. d 10% of the population of american alligators in an area have the recessive trait albinism. a massive flood results in the death of 80% of the population. of the remaining population, 60% have the recessive trait of albinism.
