TLDR
The results imply that genetic influence may operate to affect the degree of expressed preference, while the side of preference may not be genetically encoded, and suggest that lateral preferences for limb and sense organ may not been due to a single causal mechanism.Abstract:
Hand, eye, foot, and ear preference were examined in a sample of 459 biologically related parent-offspring triads and 434 sibling pairs. Intercorrelations were computed using the side of preference as the dependent variables and then again using the absolute strength of the displayed preference irrespective of side. The directional analyses did not show strong patterns of familial similarities; however, relatives did tend to resemble each other in the degree of lateralization manifested. Maternal and paternal resemblance to offspring vary over the four indices of laterality, and there are some suggestions of sex-specific interactions. These results imply that genetic influence may operate to affect the degree of expressed preference, while the side of preference may not be genetically encoded. These findings also suggest that lateral preferences for limb and sense organ may not be due to a single causal mechanism.read more

The lateral preference inventory for measurement of handedness, footedness, eyedness, and earedness: Norms for young adults
TL;DR: The Lateral Preference Inventory (LPI) as discussed by the authors is a 16-item questionnaire that validly measures hand, foot, eye, and ear preference, and has been used to measure laterality.

Left-handedness: a marker for decreased survival fitness.
Stanley Coren,Diane F. Halpern +1 more
TL;DR: Evidence suggests that left-handedness may be a marker for birth stress related neuropathy, developmental delays and irregularities, and deficiencies in the immune system due to the intrauterine hormonal environment.

Handedness, language dominance and aphasia: a genetic model.
TL;DR: The same model is fitted, by means of a number of minor conceptual extensions, to data from the literature on the relationship of handedness to language dominance, acute and permanent aphasia, and visual processing dominance.

Sexual orientation, fraternal birth order, and the maternal immune hypothesis: a review.
TL;DR: Evidence in favor of the maternal immune hypothesis of FBO is reviewed, including recent research showing that mothers of boys develop an immune response to one Y-linked protein important in male fetal development, and that this immune effect becomes increasingly likely with each additional boy to which a mother gives birth.

TL;DR: This pattern of hand-eye association poses problems for genetic models of cerebral lateralisation, which must invoke pleiotropic alleles at a single locus or epistatic interactions between multiple loci.

A classification of hand preference by association analysis.
TL;DR: An association analysis was made of the responses of young adults to a hand-preference questionnaire and it is believed to demonstrate that hand preference is distributed continuously and not discretely.

Reliability and validity of some handedness questionnaire items
TL;DR: Twenty-three items have been scaled for reliability and validity and for the frequency of right hand preference by predominantly left handed people and certain items are recommended for inclusion on future handedness questionnaires.

The psychology of left and right
TL;DR: The authors argue that the ability to tell left from right depends ultimately on a bodily asymmetry, such as preference for one or the other hand, or dominance of one side of the brain.

The dominant eye.

TL;DR: Although its functional significance has not yet been ascertained, patterns of ocular dominance have been shown to be related to a large number of perceptual, performance, and clinical phenomena.
