Read the following statements regarding chromosomal disorders : A. Aneuploidy arises due to the failure of segregation of chromatids during cell division. B. Polyploidy results from the failure of cytokinesis after the telophase stage of cell division. C. Down's syndrome is a chromosomal disorder caused by monosomy of chromosome 21. D. Individuals with Klinefelter's syndrome have a karyotype of 47, XXY and are steril

Step-by-step solution

Statement A is correct. Aneuploidy arises due to the failure of segregation of chromatids during the cell division cycle, which results in the gain or loss of a chromosome(s). Statement B is correct. Polyploidy results from the failure of cytokinesis after the telophase stage of cell division, leading to an increase in a whole set of chromosomes in an organism. Statement C is incorrect. Down's syndrome is a chromosomal disorder caused by the presence of an additional copy of chromosome 21, which is known as trisomy
