Study Notes
Genetics Basics
- A Punnett square is a graphical representation of the possible genotypes of offspring from a cross between two parents, used to predict the probability of different traits being expressed.
Traits and Inheritance
- A dominant trait is one that will be expressed if an individual has one copy of the dominant allele, even if they also have a recessive allele.
- A recessive trait is one that will only be expressed if an individual has two copies of the recessive allele.
Chromosomes and DNA
- A chromosome is a thread-like structure made up of DNA and proteins that carries genetic information in the nucleus of living cells.
