Y-Chromosome Inheritance of Hairy Ears

Abstract

When maintained in darkness, premolt specimens of Gecarcinus lateralis, with or without eyestalks, show variations in level of activity according to six distinct stages. Furthermore, in darkness the rhythmic pattern of premolt crabs with eyestalks resembles that of eyestalkless premolt crabs, the intervals between principal bursts of activity being generally shorter than in nonpremolt crabs.
