Geographical variation in song is a common feature of populations of territorial songbirds.
Non-response is a common feature of population-based HIV surveys [9], [10], [11].
Transition matrices M resulting from this model are generally square, due to the fixed population size (a common feature of many population genetic models, compare [ 3]).
Additionally, the study did not consider hierarchical population structure, a rather common feature of natural populations with important implications for population genetics inferences (Robertson 1975).
Our quantitative PCR assays indicate that the expansion of the var2csa sub-family is a common feature of natural populations of P.falciparum isolates.
Whole genome duplication, which results in polyploidy, is a common feature of plant populations and a recurring event in the evolution of flowering plants.
Reproductive skew, the uneven distribution of reproductive success among individuals, is a common feature of many animal populations.
Reproductive skew, the uneven distribution of reproductive success among individuals, is a common feature of many animal populations [ 6]. High male reproductive skew occurs if most females show a preference for a single male (or a few males) in the population, or, in turn, if single males can monopolize the majority of receptive females.
Unusual ploidy states also are a common feature of tumor cell populations, where mitotic collapse (Gordon et al. 2012) and/or telomere defects (Davoli and De Lange 2012) yield tetraploids that ultimately produce aneuploid progeny cells, some of which outcompete the surrounding cells.
This mutL finding increases to three the mutator types found in chemostat populations (mutS and mutY were previously found [ Notley-McRobb, Seeto, et al. 2002]) so this form of temporary enrichment of mutators is a common feature of a rapidly evolving population.
"Sight loss will be a more common feature of society because of our ageing population.
