Revision of 2020 Guppy Genetics Article

I revised my 2020 article ‘Breeding Guppies: Genetic Pitfalls and Successes‘.  Revision contains same basic material, but I simplified article.  I spent more time discussing popular mutations that can perplex beginners.  And I down-sized a complicated discussion on the genetics of swordtail guppies.   It was not that relevant in successfully outcrossing my beautiful delta-tail females (Photo) with male swordtail guppies.   These outcrosses were wildly successful and I had no trouble breeding out the swordtail trait.
