One strain of periwinkleplants has green leaves and another strain has white leaves. Bothstrains are true-breeding. You do not know if the phenotypicdifference is due to alleles of a nuclear gene or an organellar gene.The two strains were analyzed using reciprocal crosses, and thefollowing results were obtained:A plant with green leaves is pollinated by a plant with whiteleaves: all offspring have green leaves.A plant with white leaves is pollinated by a plant with greenleaves: all offspring have white leaves. Is this pattern of inheritance consistent with simple Mendelianinheritance, where green is dominant to white, and/or is it consistentwith maternal inheritance?

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.
