Stereociliary Myosin-1c Receptors Are Sensitive to Calcium Chelation and Absent from Cadherin 23 Mutant Mice [PDF]
, 2006 The identities of some of the constituents of the hair-cell transduction apparatus have been elucidated only recently. The molecular motor myosin-1c (Myo1c) functions in adaptation of the hair-cell response to sustained mechanical stimuli and is ...

Histocompatibility Genetics of Bullfrog Populations [PDF]
Evolution, 1961 Genetic studies of anuran species have been limited for the most part by failure of the F1 generation to reach maturity under laboratory conditions. Thus data on backcross and F2 progenies are not available and the mode of inheritance even of overt traits such as pigment patterns remains problematical (Anderson and Volpe, 1958).
