  • Genetics
  • What is Genetics Genetics is the scientific study of heredity. Heredity is what makes each species unique.
  • Gregor Mendel Austrian Monk Famous for his work with pea plants He is known as the father of genetics
  • Mendel’s Work Mendel used true-breeding plants which means if they were left to breed with themselves they would produce offspring identical to themselves. Mendel studied 7 different traits in pea plants. A trait is a specific characteristic that varies from one individual to another.
  • The Principle of Dominance The principle of dominance states that some alleles are dominant and others are recessive. Dominant alleles are always expressed. Recessive alleles are only expressed if both alleles are recessive.
  • Probability & Genetics Probability is the likelihood that an event will happen. The principle of probability can be used to predict the outcomes of genetic crosses.
  • Punnett Squares Diagram used to predict genetic crosses. Individuals with identical alleles are called homozygous Individuals with different alleles are called heterozygous Phenotype – physical characteristic Genotype – genetic makeup
  • Mendel’s Principles The inheritance of biological characteristics are determined by genes. For two or more forms of a gene, dominance and recessive forms may exist. Most sexually reproductive organisms have two sets of genes that separate during gamete formation. Alleles segregate independently.
