Michael Frederic Guyer (1874–1959) was an American cytologist and zoologist.
Guyer was professor of zoology at the University of Wisconsin.[1] In 1902, he independently discovered Mendel's laws from the cytology of spermatogenesis in pigeon hybrids.[2][3]
Between 1918 and 1924, Guyer with Elizabeth A. Smith performed experiments attempting to demonstrate Lamarckism in which fowl serum antibodies for rabbit lens-protein were injected into pregnant rabbits which resulted in defects in the eyes of some of their offspring that were inherited through eight generations.[4] Their experiments were criticized and were not repeated by other scientists.[5]
Guyer was an eugenicist.[6]
