1. The conclusion to be drawn from these experiments is that the male plants are heterogametic and the female plants homogametic.

2. That the haploid animals will become males, the diploid ones females, is an empirical fact which has so far been considered to be related to the difference in the chromosome number itself.

3. More frequently, however, the fungi were of different sexes, zygospore only being formed when threads of different mycelia were paired.

4. In the course of these investigations a quantitative differentiation was also found to occur, the different plus- and minus-mycelia being of different strength,

5. The plus gametes secrete gamones which attract the minus gametes, and these in their turn produce gamones which activate the plus gametes and cause them to throw off their organs of movement and get attached.

6. That this is really true has been demonstrated by experiment with filtrates or extracts of both kinds of gametes.

7. In each type of heterozygote two different hormones are formed corresponding to the two alleles, which therefore may be considered to be simultaneously dominant.

8. The sex chromosomes, which at meiosis separate from each other in a regular way, represent the switch mechanism that decides whether the development of the individual shall go in a female or in a male direction.

9. It is probable that the X-chromosome in man is composed of two parts, one of which is specific for the X-chromosome, the other part being homologous with a corresponding segment in the Y-chromosome.

10. We have just stated that certain diseases are absolutely X-linked, because the genes in question are located in the segment which is specific for the X-chromosome.

11. If those alleles which are recessive to W are combined, no dominance occurs, the heterozygotes being intermediate.

12. As regards the white-series in the fruit fly we have the complication that in this case it is a question of sex-linked inheritance, the locus in question being situated in the X-chromosome.

13. This implies that none of the recessive properties of the parents appear, nor will the hybrid be intermediate either, but will show those characters which are induced by dominant alleles of the recessive genes in question.

14. That the result must be of this kind is evident from the above simple diagram, in which the lines indicate a certain chromosome pair and the dots, loci.

15. In such cases it may be otherwise difficult to decide whether we have to deal with multiple alleles or strongly linked genes.
