3. Fruit flies are organisms commonly used in genetic studies. They reproduce quickly and have several traits

that can be measured. One trait is the vestigial wing trait, which is recessive. Most flies have red eyes, but

the sepia eye trait is recessive.

A fly that is heterozygous for both traits (GgEe) is crossed with one that has vestigial wings and sepia eyes

(eeee). Set up a Punnett square and list the phenotypic ratio of the offspring.

How many are normal wings, red eyes?

How many are normal wings, sepia eyes?

How many are vestigial wings, red eyes?

How many are vestigial wings, sepia eyes?

From the Punnet square: there are four normal wing, red eyes: GgEe, four normal wings, sepia eyes: Ggee, four vestigial wings, red eyes: ggEe and four vestigial wings, sepia eyes: gege

Recessive and Dominant traits

  • Recessive traits are characters that appear on if the dominant trait is absent
  • Dominant traits are characters that appear in every generation
  • A Punnet square is a square that shows the product of a cross between two or more alleles.

From the Punnet square attached;

  1. There are four normal wing, red eyes: GgEe
  2. There are four normal wings, sepia eyes: Ggee
  3. There are four vestigial wings, red eyes: ggEe
  4. There are four vestigial wings, sepia eyes: gege
