There are genes that determine sex ratios. These genes can be disrupted. Here's link to scientific article
on MSD (Maternal Sex Ratio Distorters).
While we're at it, I've just got to show pictures of my females guppies. These are samples of the F1 from a Blue Grass strain that I imported from Thailand (ATFG) last summer.
No chance of confusing these beauties with Mosquito Fish!
