Abstract

The normal (wild type) eye color in Drosophila is red. In Part 2 of this series, we described some mutants in which the colour is variable - such as white, brown, scarlet, etc. We also discussed that some of these eye colour phenotypes are due to genes present on different chromosomes. Now let us study the inheritance of eye colour in D. melanogaster in more detail. All the experiments discussed in this article are based on the general protocol that was discussed in Part 3 of the series. In that article, we described three simple experiments aimed at elucidating the pattern of inheritance of traits controlled by unlinked autosomal genes and by genes located on the X chromosome. The experiments described here are aimed at analyzing more complex situations where different genes interact to produce a particular phenotype, or when genes are linked (i.e. they are located near each other on the same chromosome, such that their transmission in gametes is not entirely independent).
