                              After Completing His Work With Peas , Mendel Turned To Experimenting With Honey Bees To Extend His Work To Animals . He Produced A Hybrid Strain But Failed To Generate A Clear Picture Of Their Heredity Because Of The Difficulties In Controlling Mating Behavior Of Queen Bees .
