Mendel’s Law of Inheritance
Learning Objectives
By the end of this lesson, the learner should be able to:
Describe the methods Mendel utilized in his research that led to his success in understanding the process of inheritance
Introduction
- By crossing purple and white pea plants, Mendel found the offspring were purple rather than mixed, indicating one color was dominant over the other.
- Mendel’s Law of Segregation states individuals possess two alleles and a parent passes only one allele to his/her offspring.
- Mendel’s Law of Independent Assortment states the inheritance of one pair of factors ( genes ) is independent of the inheritance of the other pair.
- If the two alleles are identical, the individual is called homozygous for the trait; if the two alleles are different, the individual is called heterozygous.
- Mendel cross-bred dihybrids and found that traits were inherited independently of each other
Key Terms
- homozygous: of an organism in which both copies of a given gene have the same allele
- heterozygous: of an organism which has two different alleles of a given gene
- allele: one of a number of alternative forms of the same gene occupying a given position on a chromosome
