Chapter 23, Problem 6TYU
In the 1700s and 1800s, royalty in Europe often married their close relatives; furthermore, recessive genetic diseases such as hemophilia showed up much more often among royals than in the general population. Explain the likely connection.

Fanconi anemia is an autosomal recessive disease caused by a mutation in a single gene.
It's a disease of the bone marrow.
It results in decreased production of all types of blood cells.
How can we tell from the pedigree that it is autosomal recessive?
The following pedigree illustrates the inheritance of Tay-Sachs disease
in four generations of a family. Interpret the pedigree and determine
whether the trait is dominant or recessive. What happened in the third
generation?
The pedigree shows inheritance of an autosomal recessive disease in an extended family. Assume unrelated individuals marrying into the
family do not carry the disease, unless there is reason to believe otherwise.
What is the chance that IV-3 and IV-4 will have a child with the disease?
Individuals I-1, Il-5, III-5 and III-16 have the disease.

- Queen Victoria had 1 (Leopold) out of four male offspring with hemophilia. What was the probability of this scenario? Hemophilia is known as "The royal disease" because many of the European royal families had members afflicted with it. A really famous case was Queen Victoria's (1819-1901) descendants who spread the disease across Europe, from Spain to Russia. You can see the pedigree of Queen Victoria's family here:Hemophilia is an X-linked recessive disease.
