在埃及伊蚊的阿克拉品系中，男性决定因素M和性连锁骚扰基因D分别被确定为身份。它们在Y染色体上的位置是根据彼此和Giemsa C[构成异染色质]-带的关系来定义的。M总是与着丝粒一起遗传，而D则朝向中间带。大约1.2%的重组发生在M和D之间，但在以交叉远端定位而闻名的染色体中，两者显然不一定像这可能暗示的那样在细胞学上紧密相连。关于M和D区域重组的遗传效应的证据也被考虑在内。
The separate identities of the male-determining factor, M, and the sex-linked Distorter gene, D, are established in an Accra strain of A. aegypti. Their positions in the Y chromosome are defined in relation to each other and to Giemsa C[constitutive heterochromatin]-bands. M is invariably inherited with the centromere, whereas D lies towards the intercalary band. Approximately 1.2% recombination occurs between M and D but, in a chromosome known for its distal localization of chiasmata, the 2 are apparently not necessarily as closely linked cytologically as this might imply. Evidence on the genetic effects of recombination in the region of M and D is also considered.
