ability of offspring inheriting specific traits. Pedigree charts trace inheritance patterns across generations, useful for identifying dominant, recessive, or sex-linked traits. Factors Affecting Patterns of Heredity While the patterns outlined are foundational, several factors can influence
cribe how traits are inherited through discrete units, now known as genes. Law of Segregation: Each individual possesses two alleles for a given trait, which segregate during gamete formation, ensuring each gamete carries only one allele. Law of Independent Assortment: Genes for different trai
