Richard Benedikt Goldschmidt was a German-American #zoologist who specialized in #heredity.
Published
He studied the #X-chromosomes of #butterflies. He produced a theory, now discredited, that there were more decisive factors in #inheritance than the qualities of the individual #genes..
He held that the serial pattern of the #chromosomes and the chemical configuration of the chromosome molecule were more important factors.
His experiments with the Gypsy Moth revealed that much #geographical variation is #genetic and not #environmental in origin.
However, he was able with high #temperature to produce #phenotypes in fruit flies, and demonstrate an environmental factor could mimic some of the effects of genetic #mutation, though not inheritable.
