Parallel evolution and inheritance of quantitative traits.
Parallel phenotypic evolution, the independent evolution of the same trait in closely related lineages, is interesting because it tells us about the contribution of natural selection to phenotypic evolution. Haldane and others have proposed that parallel evolution also results from a second process, the similarly biased production of genetic variation in close relatives, an idea that has receiv...
متن کاملInheritance Patterns, Dominance and Cross-Resistance of Cry1Ab- and Cry1Ac-Selected Ostrinia furnacalis (Guenée)
Two colonies of Asian corn borer, Ostrinia furnacalis (Guenée), artificially selected from a Bt-susceptible colony (ACB-BtS) for resistance to Cry1Ab (ACB-AbR) and Cry1Ac (ACB-AcR) toxins, were used to analyze inheritance patterns of resistance to Cry1 toxins. ACB-AbR and ACB-AcR evolved significant levels of resistance, with resistance ratios (RR) of 39-fold and 78.8-fold to Cry1Ab and Cry1Ac,...
متن کاملSingle-gene speciation with pleiotropy: effects of allele dominance, population size, and delayed inheritance.
Single-gene speciation is considered to be unlikely, but an excellent example is found in land snails, in which a gene for left-right reversal has given rise to new species multiple times. This reversal might be facilitated by their small population sizes and maternal effect (i.e., "delayed inheritance," in which an individual's phenotype is determined by the genotype of its mother). Recent evi...
متن کاملPartial Dominance , Pleiotropism , and Epistasis in the Inheritance of the High - Oleate Trait in Peanut
Earlier reports of the high-oleate (low-linoleate) trait in peanut (Arachis hypogaea L.) indicated that it was controlled by completely dominant gene action. However, linoleate content intermediate to that in lowand normal-linoleate seeds was found among progeny when the trait was backcrossed into five virginia-type cultivars, suggesting partial dominance of the gene controlling the trait. Alth...
متن کاملEvolutionary Stability for Interactions among Kin under Quantitative Inheritance.
The theory of evolutionarily stable strategies (ESS) predicts the long-term evolutionary outcome of frequency-dependent selection by making a number of simplifying assumptions about the genetic basis of inheritance. I use a symmetrized multilocus model of quantitative inheritance without mutation to analyze the results of interactions between pairs of related individuals and compare the equilib...
