Study Notes
Sex Determination
- Sex chromosomes are X and Y, which determine whether an individual is male or female
- XX combination of chromosomes leads to the development of female characteristics
- XY combination of chromosomes leads to the development of male characteristics
Chromosome Inheritance
- During meiosis, a sperm cell has a 50% probability of receiving an X-chromosome
Genetic Diagrams
- Genetic diagrams are used to illustrate the inheritance of traits and predict the probability of certain characteristics being passed down from one generation to the next
