The achoo syndrome (sneezing in response to bright light) and trembling chin (triggered by anxiety) are both dominant traits in humans. A. What is the probability that the first child of parents heterozygous for both the achoo gene and trembling chin will have achoo syndrome but lack trembling chin? B. If the same couple decides to have five children what is the probability that at most three will have achoo syndrome? C. If the same couple decides to have five children what is the probability that at most three will have achoo syndrome?

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.
