...…likely to exist as well, it is expected that with According to the Resource Allocation Theory of ongoing selection for high production efficiency Beilharz et al. (1993), when (internal and/or exteronly, the occurrence and magnitude of undesirable nal) resources are limited, a compromise has to…...

...This genetic correlation may arise from linked gene complexes, pleiotropy (where a single gene affects several traits), or selection of genotypes favouring allocation of finite resources to different functions (Beilharz et al., 1993; Thorpe, 2004)....

...According to the Resource Allocation Theory developed by Beilharz et al. (1993), when the amount of resources increases (because of a favorable environment) these resources will be used by the organism to raise fitness: “organisms respond to natural selection until fitness can improve no more....

...Selection for high fitness by natural selection will lead to intermediate optimal values for the fitness components and heterozygosity which imparts a buffering capacity to a wide range of environments (Dunnington, 1990; Beilharz et al., 1993)....
