Being Well-Born |Michael F. Guyer

Inheritance of Characteristics in Domestic Fowl |Charles Benedict Davenport
The heterozygote produced by crossing these forms is intermediate in size and appearance.

Mendelism |Reginald Crundall Punnett
But in a heterozygote potency is usually more or less reduced.

Inheritance of Characteristics in Domestic Fowl |Charles Benedict Davenport

Some are probably matings of two heterozygotes, others of two recessives, and others still of a recessive with a heterozygote.
