A fruit fly, also known as Drosophila Melanogaster, has two compound eyes that are each made up of 800 unit eyes. These unit eyes are called ommatidia. Each ommatidium (sing.) contains eight photoreceptors labeled R1-R8.

How many eyes do flies have?

Flies have 5 eyes! Two of these being compound eyes consisting of many lenses. The other three (ocelli) are single lens eyes located in a triangle form above and in between the two compound eyes, on the top of the head.


What was the result when Morgan mated a white fruit fly with a red eyed female fruit fly?

When Morgan mated a white-eyed male fruit fly with a red-eyed female fruit fly, the first generation offspring all had red eyes. In the next generation, because females would have the X chromosome for white eyes, about half the offspring would have white eyes. The offspring with white eyes were all male, meaning he discovered eye color in fruit flies showed a sex-linked trait. The result of this was a generation of red eyed and white eyed individuals. If the red eyed female was heterozygous, this is possible.

What are some characteristics of the Drosophila Melanogaster?

Drosophila melanogaster is a small fly that is often found near fruit. They are often know as fruit or vinegar flies. The flies have red eyes and are a yellowish color.


What is the genotype of a red-eyed male fruit fly?

Red eyes is a dominant sex-linked gene in the fruit fly. Males with red eyes have the genotype XRY, where R is for the red gene.


What was the result when Morgan mated white-eyed fruit fly with a red-eye female fruit fly?

All the offspring had red eyes. The white eye trait is recessive, so it did not appear in the offspring.

Where is the gene for fruit flies eye color?

The gene for fruit fly eye color is located on the X chromosome. It codes for a protein called "eye color," which determines the pigmentation in the eyes of the fruit fly. Mutations in this gene can lead to different eye colors in fruit flies.


What offspring would result from a cross of a homozygous red-eyed female fruit fly and a vermilion-eyed male fruit fly?

All offspring would have red eyes because the gene for red eyes is dominant over the gene for vermilion eyes. The offspring would all be heterozygous for eye color, inheriting one red-eyed allele from the female and one vermilion-eyed allele from the male.
