Study Notes
Mendel's Study and the Law of Independent Assortment
- Mendel studied the inheritance of two different traits, each with two alleles, to formulate the Law of Independent Assortment.
- During fertilization, allele pairs assort independently, resulting in a random combination of alleles from each parent.
Characteristics of the Law of Independent Assortment
- The Law of Independent Assortment results in a phenotypic ratio of 9:3:3:1.
- This law results in 16 different genotypes.
Physical Basis and Formulation
- The physical basis for the Law of Independent Assortment is the random orientation of chromosomes during metaphase I of meiosis.
- Mendel formulated the Law of Independent Assortment after discovering the Law of Segregation.
Key Principles
- The Law of Independent Assortment states that allele pairs assort independently during fertilization, resulting in a random combination of alleles.
- Mendel performed a dihybrid cross experiment, crossing two pea plants with different traits, to study the Law of Independent Assortment.
