By comparing mitochondrial DNA (mtDNA) of living people and/or of skeletons of non-living people, researchers can analyze samples to determine their ancestry. Which of the following statement correctly describes the inheritance pattern of mtDNA? Select one: a. mtDNA is transcribed from cpDNA outside of the nucleus. b. An egg contains mitochondria and a sperm cell does not contain any mitochondria. c. An egg is much larger than a sperm and therefore contains more mitochondria, passing its mtDNA to the offspring. d. An egg contributes half of the DNA and all of its organelles in the cytoplasm to the zygote.
