You capture several interesting insects from a population in your yard. By inbreeding, you develop true breeding strains that differ only in the shape of their wings - one strain has round wings while the other strain has oval wings. How might you demonstrate that Mendel's principles apply to your insects?

#Unit 8. Inheritance Biology
  1. Set up a monohybrid cross and determine if your f2 results are predicted by 3:1 ratio based on the law of segregation
  2. Set up a dihybrid cross and determine if your F2 results are predicted by a 9:3:3:1 ratio based on the law of independent assortment.
  3. Set a test cross to demonstrate that your traits breed true.
  4. Set up a two point test cross to demonstrate that your genes are linked.
