WebFecundity selection, also known as fertility selection, is the fitness advantage resulting from selection on traits that increases the number of offspring (i.e. fecundity). Charles Darwin … WebThese are income breeders, found usually in low latitudes (tropical and subtropical areas), but also in high productive temperate zones, and normally showing protracted spawning seasons and reduced seasonality. These strategies determine the different egg production traits; thus capital breeders use to have determinate fecundity, group ...
