Genetics The study of heredity (starting text page 86) Gregor Mendel 1800’s Observed pea plants Noticed sometimes plants had traits similar to parents and sometimes they did not Mendel’s work formed the foundation of genetics, the study of heredity Know the difference TT Tt tt Tips on Mendel Mendel realized that individual factors must control inheritance of traits in plants The traits exist in pairs. Male and Female parents contribute each trait. Some traits are dominant and mask or hide the other recessive traits. Chromosome Theory of Inheritance States that genes are carried from parents to offspring on chromosomes Dominant or Recessive? Heterozygous or Homozygous? Words to know Purebred Traits Genes Heredity Filial Allele P Generation F-1 Generation F-2 Generation Hybrid Phenotype Genotype
