During one of the genetics lab, you notice a few Drosophila fruit fly that has a rainbow body. You transfer the rainbow bodies flies into a separate vial. That vial of rainbow-bodies flies is left untouched for several months. As all flies in the vial continue to be blue-bodied, you assume they are true-breeding (homozygous). You want to determine the mode of inheritance of rainbow body flies so set up crosses using wild-type flies. You obtained 120 flies in each of your F1 crosses, fill in the tables with the expected numbers for F1, if the rainbow body trait is: wild-type female x Mutant male  Male Female wild type     mutant      wild type male-mutant female Male Female wild type     mutant

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.
