In people with maple syrup urine disease, the body is unable tometabolize the amino acids leucine, isoleucine, and valine. One ofthe symptoms is that the urine smells like maple syrup. An unaffected couple produced six children in the following order: unaffecteddaughter, affected daughter, unaffected son, unaffected son, affectedson, and unaffected son. The youngest unaffected son and an unaffected woman have three children in the following order: affecteddaughter, unaffected daughter, and unaffected son. Draw a pedigreethat describes this family. What type of inheritance (dominant orrecessive) would you propose to explain maple syrup urine disease?

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.
