Explanation:
A karyotype is defined as the size, shape, and number of chromosomes present in an organism.
An analysis is usually done on a karyotype to see if individuals have abnormal numbers or sizes of chromosomes. Such abnormalities may arise from;
Deletion: which implies that a chromosomal part is missing.
Duplication: where parts of a chromosome are repeated.
Translocation: which occurs when a chromosomal part breaks off and gets attached to another chromosome.
Nondisjunction: in which chromosomes do not separate from the parent cells.
Common chromosomal disorders arising from these abnormalities include;
Down's syndrome
Edwards syndrome
Turner's syndrome
Klinefelter syndrome
Prada-willi syndrome
Cri-du-chat syndrome
Patau's syndrome
