Summary

Gametogony and spermatogenesis of A. dissimilis and A. galli were studied. It was found that the chromosome number of A. dissimilis is 2n=10 for female specimens and 2n=9 for male ones.

The chromosome number of A. galli is also 2n=10 for female specimens and 2n=9 for male ones.

Comparison of the relative length of chromosomes in the chromosome set, expressed in percentages, shows nearly equal magnitudes for both species.

Spermatogenesis processes were studied. It was found that they run a similar course in both species.

In the following stages of gametogony and spermatogenesis differences between the two species are not discovered.
