Male limited precocious puberty results from a rare, sex-limited autosomal allele (P) that is dominant over the allele for normal puberty (p) and is expressed only in males. Jack undergoes precocious puberty but his sister Janice undergoes puberty at the normal time. Jack's mother Joanna has one brother John who underwent precocious puberty. Jack's father underwent normal puberty. In this scenario, Jack's sister can be Pp or pp. True False

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.
