Although it may be true for the small number of mutations listed in the following section, the fact stated on the Drosophila page stating that male fruit flies do not show meiotic recombination is false. For the trait vermillion eyes (which is simply a brighter red than the wild-type red), the males are in fact the only ones to show recombinance. It takes two generations to see this trait appear when white virgin females are mated with vermillion eyed males. The first generation will show all females will have red (wild type) eyes and all of the males will have white eyes. This also displays the fact that vermillion eyes is a sex-linked recessive trait. When the resulting males and females from F1 are mated, only 1/4 of their offspring is predicted to have vermillion eyes, all of which are male. Therefore, it is incorrect to say that males do not show meiotic recombination. 

There are also many more mutations that are not listed on the Wikipedia page. Also, for each mutation, there are hundreds of different alleles, most of which are not listed.

Also, I find the fact that the section entitled "genetic markers" really should be titled alleles, and that it is missing thousands of alleles and their corresponding codes. Vermillion eyes, bar eyes, scarlet eyes, miniature wings, etc.
