Genetics

• Mendels 3 laws of inheritance are:

  Law of dominance

  Law of segregation

  Law of independent assortment
• The law of dominance states that one allele is dominant over the other
• The law of segregation states that during gamete formation, homologous chromosomes separate so that each gamete receives only one copy of each gene.
• The law of independent assortment states that genes on different chromosomes can be inherited independently from one another.
• Epistasis is the interaction between two genes that affects the phenotype of the offspring
• PCR is used to amplify a small amount of DNA into a large amount of DNA
• The steps of PCR are denaturation, annealing, and extension
