Has TCE observed whether hybrids of Chinese and common forms [of geese] were wilder, or less tame, than both parents?
Down Bromley Kent
Will you forgive me troubling you with a question, which you can answer by “yes” or “no”. Did you observe that your hybrids between the Chinese & common form, were at all wilder or less tame than both parents? I have been informed that this is sometimes the case with hybrids, as with those from common & Musk Duck.

- f2 2164.f2Eyton had described these hybrid geese in Eyton 1837b and 1840. The question posed in the letter was evidently answered by Eyton, for CD reported that the offspring were not wilder than their parents (Natural selection, p. 486).
