John Nguyen Fruit Flies Lab Report Sec. 0008 Introduction: Fruit Flies—Mode of Inheritance In the experiment we were conducting, we were trying to find the mode of inheritance in the offspring from the different types of fruit flies ( Drosophila melanogaster ) we were given. We were crossing two different types of fruit flies—wild-type males and mutant sepia females. We came up with four different hypotheses to determine whether the mutant trait (sepia) was autosomal/sex-linked recessive or autosomal/sex-linked dominant. After we conducted our hypotheses and drew out the Punnett squares, we had to choose the hypotheses that generated the same outcome (which turned out to be the autosomal dominant and sex-linked dominant hypotheses). After that, we then drew out the reciprocal Punnett squares of those results and with this information we could generate a unique prediction for each of the hypotheses. The first hypothesis is that the sepia mutation phenotype is an autosomal dominant trait. The genotypes of the parents were wild-type male (aa) and sepia female (AA). The genotypes of the offspring
