Linearity Versus nonlinearity of offspring-parent regression: an experimental study of Drosophila melanogaster.
An experiment was conducted to investigate the offspring-parent regression for three quantitative traits (weight, abdominal bristles and wing length) in Drosophila melanogaster. Linear and polynomial models were fitted for the regressions of a character in offspring on both parents. It is demonstrated that responses by the characters to selection predicted by the nonlinear regressions may diffe...
متن کاملParent–offspring conflict
Is this soap opera or science? It can be both, but in evolutionary biology it refers to the subtly different ways natural selection acts on genes expressed in parents and their offspring. To give a concrete example, consider a parent with two offspring: other things being equal, the parent is likely to be under natural selection to give equal amounts of food to each of its young. But natural se...

متن کاملThe origins of parent-offspring signalling
The solicitation of food by young from their parents is a widespread phenomenon in species with parental care. This solicitation is often interpreted as being an honest signal of need, maintained by a costly ''handicap'' (Kilner & Johnstone, 1997). Here we address the question of how such handicap signals can originate. We identify a threshold that must first be surpassed, and suggest a method ...
متن کاملAntagonistic Parent-Offspring Co-Adaptation
BACKGROUND In species across taxa, offspring have means to influence parental investment (PI). PI thus evolves as an interacting phenotype and indirect genetic effects may strongly affect the co-evolutionary dynamics of offspring and parental behaviors. Evolutionary theory focused on explaining how exaggerated offspring solicitation can be understood as resolution of parent-offspring conflict, ...
