## Mendel's Laws ### Mendel's Law of Segregation - During gamete formation, the alleles segregate from each other so that each gamete carries only one allele for each gene. ### Mendel's Law of Independent Assortment - Genes coding for different traits segregate independently during the formation of gametes. ## Sources of Variation in Gene Pool ### Monohybrid Inheritance - The inheritance of a characteristic controlled by a single gene ### Types of Inheritance #### Complete Dominance - One allele is fully dominant over the other - Examples: * "PP" = purple flower * "pp" = white flower * "Pp" = purple flower #### Co-dominance - A single gene has more than one dominant allele - Will express phenotypes for both alleles - Examples: * "WW" = white flower * "PW" = pink flower * "PP" = purple flower #### Incomplete Dominance - Neither the recessive or dominant gene is completely dominant - Producing proteins for both traits (heterozygous) - Examples: * "PP" = red flower * "Pp" = pink flower * "pp" = white flower #### Lethal Alleles - Alleles which cause the death of the organism, can be recessive or dominant - Example: "XX" #### Multiple Alleles - 3 or more possible alleles for a singular trait - Examples: * 3+ alleles for eye color * blue eyes * brown eyes * green eyes
