Evolutionary BiologyFutuyma (ecology and evolution, SUNY Stony Brook) covers such subject areas as phylogeny, paleobiology, genetic mechanisms of change and speciation, character evolution, the theory of processes and macroevolution, and new molecular perspectives. Numerous line drawings, charts, diagrams, and maps are provided. Annotation copyrighted by Book News, Inc., Portland, OR |

The variance thus depends on the gene frequencies and on the phenotypic effect
a of an allele substitution . ... In this example the effect of an allele substitution on
the phenotype is the same , no matter what other allele the individual has .

It seems possible that many of the mutations we know from their phenotypic
effects — those that alter the proportions and sizes of structures , their fusion with
or distinction from other structures , their pattern of spatial arrangement — may
well ...
