Question

A karyotype that uses FISH that shows two chromosomes, each with two colors, but in the opposite patterns, most likely indicates a:

a) Translocation
b) Duplication
c) Inversion
d) Deletion

Answer 1

A karyotype that uses FISH and shows two chromosomes, each with two colors in opposite patterns, most likely indicates a translocation.

Step-by-step explanation:

A karyotype that uses FISH and shows two chromosomes, each with two colors in opposite patterns, most likely indicates a translocation. Translocation is a chromosomal mutation where a segment of genetic material breaks off from one chromosome and reattaches to another chromosome or a different part of the same chromosome. This rearrangement of genetic material can lead to changes in gene alignment and can have various effects depending on the positions of the genes involved. In this case, the opposite pattern of colors on the two chromosomes suggests the presence of a translocation.
