As a Drosophila research geneticist, you keep stocksof flies of specific genotypes. You have a fly that hasnormal wings (dominant phenotype). Flies with shortwings are homozygous for a recessive allele of thewing-length gene. You need to know if this fly withnormal wings is pure-breeding or heterozygous forthe wing-length trait. What cross would you do todetermine the genotype, and what results would youexpect for each possible genotype?

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.
