3. Beetles of a certain species may have green, blue, or turquoise wing covers. Virgin beetles were selected from a polymorphic (i.e. not a true-breeding stock) laboratory population and mated to determine the inheritance of wing-cover color. The crosses and results were as follows: Parents blue X green blue X blue green X green blue X turquoise blue X blue 12345 6 7 8 blue X green blue X green turquoise X turquoise a. Progeny all blue 3 blue: 1 turquoise 3 green 1 turquoise 1 blue: 1 turquoise 3 blue: 1 green 1 blue: 1 green 2 blue 1 green: 1 turquoise all turquoise Explain how the genetic basis of wing-cover color in this species could be determined by one gene. b. Write the genotypes of all parents and progeny as completely as possible. (Use gene and allele symbols of your own choosing, but please define what they are.)

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.
