Imagine that you have a large collection of fruit flies divided into ten different strains. Each strain is true-breeding (homozygous) and differs from wild type flies in just one charachterstic. The only special equipment available is a magnifying glass that lets you determine the sex and traits of any fly, a large number of bottles to preform controlled matings, and an anesthetic liquid enables you to examine and sort live flies. Using only this equipment, how much could you learn about genetic makeup of the flies? Describe a series of experiments that would give you knowledge about fruit fly genetics.
