Fecundity selection, also known as fertility selection, is the fitness advantage resulting from selection on traits that increases the number of offspring (i.e. fecundity). [1] Charles Darwin formulated the theory of fecundity selection between 1871 and 1874 to explain the widespread evolution of female-biased sexual size dimorphism (SSD ...
Fecundity selection builds on that idea. This idea claims that the genetic selection of traits that increase an organism's fecundity is, in turn, advantageous to an organism's fitness. [10] Fecundity Schedule. Fecundity Schedules are data tables that display the patterns of birth amongst individuals of different ages in a population.
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
Annual plant – Plant which completes its life cycle within one growing season and then dies; Behavioral ecology – Study of the evolutionary basis for animal behavior due to ecological pressures; Ecology – Study of organisms and their environment; Life history theory – Analytical framework to study life history strategies used by organisms
The reproduction of rats follows an r-selection strategy, with many offspring, short gestation, less parental care, and a short time until sexual maturity. The same applies to mice. In r/K selection theory, selective pressures are hypothesised to drive evolution in one of two generalized directions: r - or K-selection. [2]
A mating system is a way in which a group is structured in relation to sexual behaviour. The precise meaning depends upon the context. With respect to animals, the term describes which males and females mate under which circumstances.
Selection is thus an ongoing process where deviants are selected or removed from the selection program. The main purpose of selection is to better the quality and yield of forthcoming plantations. Different approaches can be followed in the selection process of asexual plants, such as mass selection and clone selection from clone blocks.
The ability to differentiate between kin and non-kin is not necessary for kin selection in many animals. [65] However, because plants do not reliably germinate in close proximity to kin, it is thought that, within the plant kingdom, kin recognition is especially important for kin selection there, but the mechanism remains unknown.
