Genetic Loads and the Cost of Natural Selection,, Haldane was concerned with both the dynamics and the statics of evolution. He emphasized that, although evolution depends on changes of gene frequency, nevertheless at any one time the population is in approximate equilibrium for most factors.不来 发表于 2025-3-23 18:13:55

The Evolution of Dominance,tinuously being produced by mutation, other genes which modify the action of this gene will eventually be selected which will give individuals carrying the gene a phenotype resembling the favoured wild-type phenotype. Since the gene occurs initially to a large extent in the heterozygous rather thanMOTIF 发表于 2025-3-24 08:45:28

The Incomplete Binomial Distribution,sses of the distribution are either unobservable or cannot be distinguished from some other phenomenon which is not a part of the system under consideration. For instance, if we wish to study the sterility rate in a certain variety of beans, we would count the number of abortive beans as well as the填满 发表于 2025-3-24 15:03:15
Evolutionary Significance of Linkage and Epistasis,een closely located genes is stronger than that between genes far apart on the linear sequence. For this reason, closely linked genes are more likely to take similar evolutionary paths than those linked loosely. Epistasis is the functional interdependence or interaction of non alleles.

Fitness and Optimization, Darwin accepted Spencer’s expression “the survival of the fittest” as equivalent to natural selection. It, therefore, refers to those properties of species or populations which can be invoked to account for the abundance, distribution, duration, and composition of species.流动性 发表于 2025-3-25 00:02:37
