Question
Chapter 26, Problem 10TY
Summary Introduction
Introduction: The horizontal gene transfer or movement of the genetic sequences from the parent to the offspring takes place separately and not along with the transmission of DNA. It is helpful in causing variations in the progeny and results in the evolution of the organism.

What is a reasonable explanation for why some genes still remain in the mitochondria? A. The products of those genes are rapidly damaged and need to be quickly replaced. B. The products of those genes are not required for organelle function. C. The ability for lateral gene transfer ended about a billion years ago and some genes simply got “stuck” within mitochondria. D.
