You set up two populations of fruit flies (Drosophila) in the lab in large enclosures. One population is maintained in a high food condition in which food is constantly abundant and uniformly distributed, whereas the second population is maintained in a low food condition is which food is scarce and randomly distributed. You allow the populations to live and breed in the enclosures for 500 generations. Which of the following can you correctly predict to occur? a. the “sitter” allele (forS) will increase in the high food population. b. the “rover” allele (forR) will increase in the high food population. c. flies in the low food population will have higher levels of PKG compared to flies in the high food population. d. flies in the high food population will have higher levels of PKG compared to flies in the low food population. e. a and c f. b and d g. none of these

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.
