Subject:
Biology, Evolutionary Biology / Genetics, Biochemistry / Molecular Biology

In a finite population, drift is often more important than selection in removing any initial additive variance. This chapter examines the joint impact of selection, drift, and mutation on the ... More

Laurence D. Muller

in Does Aging Stop?

Published in print:
2011
Published Online:
