Studies on the selective agents operating in experimental populations ofTisbe clodiensis (Copepoda, Harpacticoida)

摘要: In order to determine the biotic selective factors affecting fitness of genotypes in polymorphic speciesT. clodiensis, five types experimental populations were utilized: (1) Populations started with equal numbers virgin females and males three (pp, pP, PP) at f(p)=f(P)=0.5 Hardy-Weinberg proportions; (2) Populations heterozygous males; (3) Populations recessive homozygous dominant females, each fertilized by same genotype; (4) Populations f(p)=0.2, f(P)=0.8 proportions; (5) One population as (4) but f(p)=0.7 f(P)=0.3.
