They describe the evidence for evolution in fossils, rocks and drug resistance, examine how evolution works (DNA, genetic variation and gene frequency, mate choices and coefficients of relatedness), the scale and products of evolution and the role of evolution in our daily lives.
Boxes are used to set off important concepts or techniques (e.g., statistical testing, combining probabilities, protein electrophoresis, calculating coefficients of relatedness).
The coefficients of relatedness in this case measure phenotypic correlation among participating behavioral actors.
sisterhood" is powerful; it is a question of coefficients of relatedness and the terms of economic survival.
Coefficients of relatedness in a social insect colony containing a queen and her progeny reveal asymmetries that result from the haplodiploid sex determination system of Hymenopterans.
Part of the procedure presented herein involves estimating "actual" variance for coefficients of relatedness, for which new estimators are developed.
To describe this, let the "coefficients of relationship [R.sub.l] and [R.sub.m]" refer to either r, [r.sub.2] or f (e.g., l and m index coefficients of relatedness and inbreeding).
The individual coefficients of relatedness or inbreeding are estimated by the general form
Thus to adequately characterize properties, we need to know what are the natural levels of variation and covariation for the two- and four-gene coefficients of relatedness, the sharing of inbreeding coefficients, and the sharing of environments (the components of X).
Coefficients of relatedness, r, were determined directly from breeding records (J.
