Crossword-Solution: SYNAPSIS 8 letters, 1 clue 🏆 scrabble score: 13

Whether the mixture of the chromosomes occurs in every resting stage of the nucleus in the successive generations of the gametocytes, or whether it occurs only in the synapsis stage preceding reduction division, it is not surprising that the colloid substance of the chromosomes should form a more or less complete intermixture, and that the two original chromosomes should not be again separated in the pure condition in which they came into contact.

From this synapsis the _lower neurone_ proceeds, its axons travelling to the anterior horn and arborising around the motor cells.

The peculiar result in this case is due to the fact that the F_1 male gets his single factor for eye color from his mother only and it is linked to or contained in a body (the X chromosome) that is involved in producing the females, while the mate of this body--the Y chromosome--is indifferent with regard to these factors, yet active as a mate to X in synapsis.

From the protracted and painstaking investigation of the German author it appears that in _Didymium_ at least, and probably _Badhamia_ synapsis immediately precedes spore-formation as in _Ceratiomyxa_; that the amoeboid issue of the spores are haploid; the nuclei of the plasmodium, diploid; that the ordinary vegetative plasmodium is accordingly sporophytic.

This is, therefore, clearly a reducing division as far as this pair is concerned, and probably for all of the other pairs, though neither the synapsis stage nor the prophase forms are so clear on this point as in some of the other species studied.
