Why doesn't an exchange between sister chromatids result in the production of a recombinant?
A) Sister chromatids are genetically identical and therefore an exchange would not show any change in phenotype
B) Sister chromatids are not genetically identical and therefore cannot exchange information
C) Sister chromatids are genetically identical and therefore cannot exchange information
D) Sister chromatids are not genetically identical and therefore an exchange would not show any change in phenotype
E) None of these explains this

Question

Quizplus · Accepted Answer

Sister chromatids are genetically identical because they are copies of the same chromosome. Therefore, any exchange of genetic material between them does not result in a change in the genetic information or phenotype, as they already contain the same alleles.
