Hey!

Start simple: understand the definitions of what you are going to be tested on (monohybrid cross, dihybrid cross, etc). I discovered a Youtube channel called the Amoeba Sisters, and I wish they'd existed when I was in college...perhaps I wouldn't have dropped my biology major...anyway...

After that, practice as many types of monohybrid crosses as possible until it comes second nature. Add another trait: dihybrid cross. Keep adding topics in.

Do some research on Queen Victoria's hemophilia (AKA Christmas's disease) and trace the trait from Queen Victoria through the royal houses of Europe (cool tie in to history is how the hemophilia of her great-grandson may be responsible for the murder of the Romanovs and end of monarchy in Russian). This will help you examine sex-linked traits and introduce pedigree. Also: the Amoeba Sisters still have amazing videos on their Youtube channel!

Please let me know if I can help- this is the third time I have coached this event! :)

This might be a kind of stupid question, but would they have Nats topics on invitational tests? In the Heredity rules they have Regional and State topics and then ones that you would only be tested on for Nats, but I don't know where invitationals would fall under. Thanks!

Invitational tests usually will not have national topics, but some might.

Hi! I am not sure what exactly I should put on my heredity cheat sheet, as this is my first year doing this event and I do not know what should be on the paper. If anyone could help, that would be wonderful. Thank you!

Cover all of the topics in the rules (but only include information that you don't have memorized). You should also maybe include a codon table/wheel in case the ES doesn't provide it in the test. Also, it may be helpful to have the History of Genetics (i.e. scientists, the Human Genome Project, etc.) as I've seen practice tests that ask questions about Watson & Crick and like Oswald Avery. Finally, you may want to include diagrams, such as: the enzymes for DNA replication, skeletal structure of nucleotides and nitrogenous bases, and maybe pedigree symbols.
