When the F1 bees were backcrossed to the inbred resistant line produced 4 types of offspring in equal numbers: ¼ if the back-cross offspring showed the complete hygienic behavior pattern ¼ of the back-cross offspring showed none of the elements of hygienic behavior ¼ of the back-cross offspring would uncap the cells of the diseased larvae but these workers would not remove the diseased larvae ¼ of the back-cross offspring would remove the diseased larvae (once the experimenter had uncapped the cells of the diseased larvae) 1. Is it possible that two gene loci are involved in the resistant behavior? Show work.

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
