Piebald rats and selection
William Ernest Castle and John Charles Phillips
Can you breed a spotted rat into a solid one, generation by generation? Castle put the question to the test, running plus and minus selection series, crossing hooded rats with wild and black Irish strains, and recording every result. A foundational experiment in heredity from the dawn of genetics. Watch inheritance revealed one careful litter at a time.
Every copy includes a printable PDF edition, a beautifully typeset book you can print, mark up in the margins, and keep on your shelf. Yours the moment you own it.
