My bad. Future Cannabis Project. Episode entitled "Hazes" at 2:01 or so is the meat of it. Mr Toad gives the creds of the study and goes more in-depth throughout the podcast.
Question about crossing two strains

Found it, thank you. It comes from here:
Molecular Cytogenetic Characterization of the Dioecious Cannabis sativa with an XY Chromosome Sex Determination System
Hemp (Cannabis sativa L.) was karyotyped using by DAPI/C-banding staining to provide chromosome measurements, and by fluorescence in situ hybridization with probes for 45 rDNA (pTa71), 5S rDNA (pCT4.2), a subtelomeric repeat (CS-1) and the Arabidopsis telomere probes. The karyotype has 18...
"The species’ estimated haploid genome sizes are 818 Mb for female plants and 843 Mb for males, indicating that the Y chromosome is larger than the X"
That's normal and to be expected. It refers to encoding of sexual characteristics. It doesn't have anything to do with other traits of interest, only that Y is larger than X. Other traits of interest are still paired in alleles in an evenly distributed manner from each parent. Normal Mendelian sexual reproduction genetics still holds.

Well that was a bit a read. Thank you. Wow, he totally misrepresents that study.Found it, thank you. It comes from here:
