Mendel’s Laws of Genetics Unit 5: Genetics Chapter 11

Gregor Mendel Father of Genetics He studied the garden pea plant – Seed color & shape, flower color, pod color & shape, and height Pea plants have male & female gametes to reproduce sexually – He could select gametes to fertilize

Mendel’s Conclusions 1. Traits are determined by genes that are passed from one generation to the next. 2. Principle of Dominance: Some alleles are dominant to other alleles 3. It is possible to have a trait that seems to have disappeared, reappear in later generations.

segregate 4. Law of Segregation: Alleles segregate (separate) during meiosis – Each gamete only gets one allele

5. Principle of Independent Assortment: Genes on different chromosomes are not connected – Alleles sort independently into gametes
