Table 1 gives the time it took for a wild type male and a wild type female to mate in each particular cross. Table 2 gives the time it took for a blind male and wild type female to mate in each cross. Table 3 gives the time it took for a blind male and a blind female to mate in each cross. And, Table 4 gives the time it took for a wild type male and a blind female to mate in each cross. Table 1 has an average copulation time of 6:31, Table 2 has an average copulation of 8:37, Table 3 has an average copulation of 6:34, and Table 4 has an average copulation of 7:12. The copulation times that are recorded as 20:00 minutes are the assays that did not initiate mating behavior during the allotted time period. Because all of the averages are relatively close to each other, and the cross containing both blind sexes is not the highest, there must be something other than sight that allows them to mate. Normal-eyed flies are denoted as W+, and white-eyed flies are denoted as W-. Time of copulation was measured by minutes:seconds.

**Note that the Table's are denoted as follows:

Crosses:
