  • Read the passages and answer the questions that follow Chromosomal abnormalities, alterations and aberrations are at the root of many inherited diseases and traits. Chromosomal abnormalities often give rise to birth defects and congenital conditions that may develop during an individual's lifetime. Examining the karyotype of chromosomes (karyotyping) in a sample of cells can allow detection of a chromosomal abnormality. The normal human chromosome contains 23 pairs of chromosomes, giving a total of 46 chromosomes in each cell, called diploid cells. Aneuploidy refers to the presence of an extra chromosome or a missing chromosome and is the most common form of chromosomal abnormality. Down syndrome, Turner syndrome, and Klinefelter's syndrome constitute the most common chromosomal abnormalities. On which of the following chromosomal disorders are based on?

    A
    Mutant allele and their defective products
    B
    Imbalance in chromosome number and chromosome arrangement
    C
    Mutant allele and chromosome arrangement
    D
    Mutant allele and imbalance in chromosome number
