Executioners tried to stab them with bayonets and then shot the in the head The story of the Romanov family is fascinating and gruesome, but what does it have to do with biology?!
Learning Objectives • Describe the story of Alexsei Romanov • Explain the link between his story and genetics • Examine the inheritance patterns seen in the Royal families across Europe
The House of Romanov Maria Romanov Tatiana Romanov Anastasia Romanov Alexandra Romanov Nicholas Romanov Alexsei Romanov Olga Romanov
Alexei Romanov • Alexsei Romanov was born in 1904, the youngest Romanov child • He appeared healthy until the age of 6 when he began to bleed from his naval • Alexsei was diagnosed with a rare genetic disease called Haemophilia • His joints would fill with blood when he hurt himself causing him extreme pain • He almost died from a haephophilic attack when he was 8 as a result of a leg injury • He was shot twice at close range during the revolution and likely bleed to death. He was 13 years old.
Punnett Squares • Punnet Squares are a way to work out the likelihood of certain inheritance patterns in the offspring of two known individuals
Task 1 • Complete the sheet ‘Genetics and The Romanovs’
Task 2 • Play ‘The Royal Blight’ Game • Each lab group will be given one of four members of the Victorian Royal Family, and will arrange marriages between their royal and one of twelve royals from other countries. • The hemophilia genotypes will be given for the royals, and the students will produce Punnett squares predicting the possible offspring from their marriage. • They will then roll a four-sided die to select one outcome, and the resultant prince or princess (F1 generation) will be “married” to another group’s prince or princess. • Complete the sheet ‘Genetic Counseling for the Royals’
