Which disorders can be observed in a human karyotype
s2008m [1.1K]

Answer:

Answered below.

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
