Choosing facial features of offspring
Genetics of the human face: Identification of large-effect single gene variants
Is Beauty in the Face of the Beholder?
Firstly, we review the facial characteristics that influence attractiveness judgements Keywords: attractiveness, mate choice, preferences, agreement, variation, .
and indirect benefits of heterozygous genes that can be passed onto offspring.
Description:Clinic director Dr Jeff Steinberg, who as a young medic was part of the team involved in the birth in Britain in of Louise Brown, the world's first test tube baby, is undeterred. Here comes the son: Remarkably, these neuroimaging studies also imply the existence of a face processing network for discrimination of non-kin from kin . Relating to faces, one study has demonstrated that facial asymmetry is positively related to self-reported number of occurrences of respiratory disease [ 35 ] and some studies have observed positive correlations between symmetry and other putative indices of underlying physical condition i. Moreover, biologists have pointed out that a selection against extreme outbreeding could be adaptive because it prevents co-adapted gene complexes from breaking up  ,  ,  ,  , .
