Non-Mendelian Patterns of Inheritance

• Genetics - the study of genes and heredity.
• Heredity - the passing of genetic information and traits from parent to offspring.
• Alleles - the different forms of a gene that controls a certain trait.
• Genes - code for specific trait.
• Dominant Traits - traits that are expressed.
• Recessive Traits - traits that are covered up.
• Homozygous - two of the same alleles.'
• Heterozygous - two different traits
• Genotype - exact pairing of alleles.
• Phenotype - expression of the trait.
• Non-Mendelian Patterns of Inheritance

  • Incomplete Dominance
  • Codominance
  • Multiple Allele
• Incomplete Dominance - Dominant allele masks the effect of the recessive one but not completely.
• Codominance - Both dominant and recessive alleles are expressed equally.
• Multiple Allele - More than two alleles can be present at a locus, resulting in more than three phenotypes.
