Question
Karyotype is used to examine chromosomes in a cell sample. It is used to see structural changes in a chromosome like deletion, duplication and therefore used in detecting a variety of genetic disorder or inherited disorder. The point mutation could not be observed from karyotype and hemophilia is caused by point mutation therefore could not be detected with karyotype. The process of crossing over is also not observed with karyotype. The diseases like Down syndrome, turner syndrome which are caused by non-disjunction of chromosomes and lead to aneuploidy could be observed with Karyotype. Therefore non-disjunction could be observed with karyotype. Hence, option c is correct.

Which of the following statements BEST describes the importance of meiosis in human evolution? Crossing over creates novel genetic sequences that can be passed to the next generation. Meiosis produces cells that contain varied and heritable DNA so that humans have variation (that ultimately allows us to adapt to changing environments). Mutation shuffles variation during meiosis ensuring that the new daughter cells are not identical to the parent cells. All of the above.
