The EABC sponsors a seminar series on the interesting and complex biological phenomena of evolutionary trade-offs, featuring phenotypic plasticity, life history evolution, and pleiotropy.  These phenomena provide an intuitive entrance into the unexpected consequences found in the genotype-phenotype map. 

Evolutionary Trade-Offs & Phenotypic Surprise

Four seminars comprise this seminar series.  Three were presented in early October, 2003, while a fourth will be presented in January, 2004.  For each seminar a brief description of the speaker and the presentation are provided below.  Additionally, the video (streaming) of each presentation is available.

phenotypic plasticity:    the capacity for marked variation in the phenotype as a result of environmental influences on the genotype during development

pleiotropy:    the phenomena of a single gene being responsible for a number of disticnt and seemingly unrelated phenotypic effects; a situation in which a single allele may affect an entire series of traits.
