Chapter 5 Heredity

Explore the concept of heredity and how traits are inherited from parent to offspring. Learn about dominant and recessive traits, genes and alleles, and the role of chromosomes in determining the genotype and phenotype of an organism. Understand the importance of probability and meiosis in the formation of sex cells.
