What is "reversions"

Usage examples of "reversions".

Consequently, sudden reversions to the perfect character of either parent would be more likely to occur with mongrels, which are descended from varieties often suddenly produced and semi-monstrous in character, than with hybrids, which are descended from species slowly and naturally produced.

Acclimatisation -- Correlation of growth -- Compensation and economy of growth -- False correlations -- Multiple, rudimentary, and lowly organised structures variable -- Parts developed in an unusual manner are highly variable: specific characters more variable than generic: secondary sexual characters variable -- Species of the same genus vary in an analogous manner -- Reversions to long-lost characters -- Summary.

Acclimatisation -- Correlation of growth -- Compensation and economy of growth -- False correlations -- Multiple, rudimentary, and lowly organised structures variable -- Parts developed in an unusual manner are highly variable: specific characters more variable than generic: secondary sexual characters variable -- Species of the same genus vary in an analogous manner -- Reversions to long lost characters -- Summary.

In the case of animals, reversions may occur in the individual with advancing age.

It might further be expected that the species of the same genus would occasionally exhibit reversions to lost ancestral characters.

In both varieties and species reversions to long-lost characters occur.
