blending inheritance
Noun
Meaning
blending inheritance (uncountable)
(biology, historical) The obsolete theory that progeny inherits any characteristic as the average of the parents' values, so for example crossing a red and a white variety of flower would yield pink-flowered offspring.
Examples
But with blending inheritance, genetic variance would be rapidly lost, making evolution by natural selection implausible.
Various hereditary mechanisms, including blending inheritance were also envisaged without being properly tested or quantified, and were later disputed.
