Mendelism / Third Edition

A clear, accessible account of Mendelian heredity and later experimental work, outlining core principles such as segregation, dominance, interaction of factors, coupling and repulsion, sex-linked inheritance, intermediates, and reversion. The author illustrates these patterns with examples and diagrams drawn from plants and animals — peas, sweet peas, fowls, rabbits, butterflies, sheep — and from human pedigrees, translating observations into genetic schemes. Chapters examine variation, evolutionary implications, practical breeding problems, and the biological basis relevant to eugenic ideas, aiming to show how experimental methods reveal lawful patterns in inheritance.
