Twin Spotting Provides Evidence of What Genetic Event

Question

Twin spotting provides evidence of what genetic event?
A) meiotic recombination
B) mitotic recombination
C) linkage
D) mutation

Accepted Answer

Twin spotting occurs when mitotic recombination occurs during embryonic development, leading to two different populations of cells with different genetic makeup in one individual. This provides evidence of mitotic recombination as the genetic event.
