In a complete dominance system: A certain dominant gene causes some people in the population to be born with 6 fingers (F) instead of 5 (f). Another dominant gene causes dwarfism (D) while normal height (d) is recessive. A father, Darren, has five fingers and is of normal height. The mother, Morgan, has 6 fingers and is also a dwarf although her mother is of normal height and has 5 fingers. What percent of the offspring will have dwarfism and have 6 fingers?

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.
