Classify each statement as true or false. A mating between SS and Ss individuals will result in all pure-breeding progeny. An individual that is Ss is pure-breeding for the S gene. Truo An individual that is SS is pure-breeding for the S gene. The progeny of a mating between two pure-breeding plants, one with the dominant characteristic caused by S, and the other with the recessive characteristic caused by s, will yield progeny with a mix of dominant and recessive characteristics.

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.
