variance is much lower than in (b), … In population (b) the chosen males on average are of higher …

… When we classify the phenotypes of the three boldness genotypes at point x: B … B and S
produce the same mean phenotype, and I individuals have a higher phenotypic value than B and …

Publisher Summary This chapter presents a review of mate choice and genetic quality,
defines mate choice, and discusses some of the key issues about how individuals can benefit …

… 1 b) signal this response in the fossil as well. Although several groups of fungi have been
documented from the fossil record, their phylogeny continues to remain problematic. …

Associated with a continued global increase in urbanization [1], anthropogenic light pollution
is an important problem [2]. However, our understanding of the ecological consequences of …

Females in a variety of species commonly mate with multiple males, and there is evidence
that they benefit by producing offspring of higher genetic quality 1 , 2 , 3 ; however, the nature …

… Kempenaers B, personal observation). Furthermore, it is unlikely that females engage in
extrapair copulations to remate with a better male ("mate sampling hypothesis"; Heg et al., 1993)…

… The intense blue plumage of male Hainan blue flycatchers (Cyornis hainanus) (a) is dramatically
more colourful than female plumage (b) in this strongly sexually dichromatic species. In …

Polymorphisms in several neurotransmitter-associated genes have been associated with
variation in human personality traits. Among the more promising of such associations is that …

Matings between close relatives often reduce the fitness of offspring, probably because
homozygosity leads to the expression of recessive deleterious alleles 1 , 2 , 3 , 4 , 5 . Studies of …
