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.

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
