Law of Segregation: Alleles separate during gamete formation. Law of Independent Assortment: Genes for different traits assort independently. 3. Important Terms Allele: Different forms of a gene. Homozygous: Identical alleles (AA or aa). Heterozygous: Different alleles (Aa). Phenotype: Physical expression of a trait. Genotype: Genetic makeup of a trait. 4. MonohybridRead More →
