Study Notes
Exam 1 Study Guide 2024
- Practice many problems, focusing on pedigrees and multiple gene problems.
- Studying through problem-solving and writing out what you know is more effective than just reviewing notes.
- Given parental genetic information, predict offspring probabilities for crosses involving:
- 1-4 genes
- Sex-linked genes
- Epistasis
- Blood types (knowing genotype designations for blood type genes is crucial)
- Given offspring information, determine parental genotypes and phenotypes.
- Given a pedigree, determine the inheritance pattern and assign correct genotypes to individuals.
- Given a genotype, identify possible gametes.
- Calculate the probability of multiple offspring having a specific phenotype in a cross.
- Understand environmental impacts on phenotypes and how twin studies inform the roles of genetics and environment in phenotype expression.
