- Common Drosophila Mutations and Their Traits - Biology Insights
The common fruit fly, Drosophila melanogaster, is a small insect used extensively in genetics research Scientists study it to understand how genetic mutations—changes in an organism’s DNA sequence—alter physical and biological traits
- Lesson Plan: Wild Type and Mutant (Fruit Fly) | Exploratorium
Introduce students to Drosophila notation according to the Primer above, or make up your own for use in class Reveal to students that the inheritance mode for the first mutation, vestigial, is recessive
- Bloomington Drosophila Stock Center: Indiana University Bloomington
More often a condensed notation is used and it is left to the user to apply the rules of segregation and sex determination to identify the genotype of each sex For example, compound 1st, or attached-X, chromosomes are commonly used to create balanced stocks of X-linked female sterile mutations
- Introduction: Drosophila—A Model System for Developmental Biology
Drosophila melanogaster, known colloquially as the fruit fly, remains one of the most commonly used model organisms for biomedical science For more than one hundred years, the low cost, rapid generation time, and excellent genetic tools have made the fly indispensable for basic research
- Fruit fly mutants: and introduction to Drosophila genetics
White was the first mutant ever discovered in flies White is a recessive mutation in the X chromosome, so it is an example of sex-linked inheritance Drosophila males (like humans) are XY, only have one X chromosome; females are XX If you cross white male flies with wild type females all the progeny would be red eyed (wild-type)
- A Short History and Description of Drosophila melanogaster Classical . . .
In naming and symbolizing chromosome aberrations, the numeral is commonly used rather than the letter when the sex chromosome is involved Females have two X chromosomes and males a single X and the Y Both sexes have two sets of the autosomal second, third, and fourth chromosomes

A dominant mutation exists that turns the antenna into a leg (crazy!) This mutation is called Antennapedia, and we abbreviate it to Antp Note that the capital A in the abbreviation tells us that the mutation is dominant The wild-type allele (where antennae are actually antennae, not legs) is symbolized by Antp +
- The Detection of Mutations in Drosophila melanogaster*
rnia Institute of Technology Pasadena, California I INTRODUCTION In the chapter we will take up the principal tests for detecting new y arising mutations in the germ cells of Drosophila melanogaster Our approach will be to outline the basic methodology for each type of mutation test presented and
