Question

Which genetic abnormally can be identified through karyotyping?

Answer 1

Karyotyping is the way toward blending and requesting every one of the chromosomes of a living being, along these lines giving an expansive preview of a person's chromosomes. Karyotypes are readied utilizing institutionalized recoloring methodology that uncover trademark basic highlights for every chromosome. Clinical cytogeneticists examine human karyotypes to distinguish net hereditary changes—peculiarities including a few megabases or a greater amount of DNA. Karyotypes can uncover changes in chromosome number related with aneuploid conditions, for example, trisomy 21. Watchful investigation of karyotypes can likewise uncover more inconspicuous auxiliary changes, for example, chromosomal erasures, duplications, translocations, or reversals. Truth be told, as therapeutic hereditary qualities turns out to be progressively coordinated with clinical solution, karyotypes are turning into a wellspring of indicative data for particular birth abandons, hereditary scatters, and even growths.

Therefore, we can conclude the answer is (d). 

Answer 2

The correct choice is D.

A karyotype is the layout of chromosomes, in size order from largest to smallest. These chromosomes are ALWAYS in pairs, meaning that it would be easy to notice which of the 23 chromosome pairs have 3 chromosomes instead of the usual pair.
