Particulate Inheritance
Captions available
The idea
Particulate inheritance holds that hereditary factors, later identified as genes, whose alternative versions are alleles, remain discrete and unblended across generations, resurfacing intact even after skipping a generation entirely.
In practice
A recessive white-flower factor, invisible in F1, reappeared in about a quarter of F2 plants.
Where people slip
A factor's disappearance in F1 is not its destruction — particulate inheritance means it persists, masked, until F2.
