Before mendel was it known that genes can be manipulated?

-

in broad sense, yes.

mendel didn't discover "genes" exactly, characteristics inherited in mathematically predictable manner. before time, assumed characteristics of offspring somehow blend of characteristics of parents through blood or other mechanism.

people had been selectively breeding plants , animals bring out specific traits long before mendel (or darwin, lived same time). in fact, darwin used selective breeding of pigeons show how traits within species can changed way illustrate theory of evolution. following website has illustration of 6 "breeds" of pigeons darwin wrote in of books "variation in animals , plants under domestication" published in 1868 http://biologylabs.utah.edu/shapiro/shap...

though mendel , darwin had no concept of genes, dna, or chromosomes (these come later), they, other people lived @ same time (and long before), knew characteristics of plants , animals manipulated.
