In previous research the inheritance patterns of synaesthesia (eg experiencing colours from graphemes) has been studied and it was concluded that synaesthesia is most likely to be the outcome of a single gene passed on the X chromosome in a dominant fashion. In addition, it has been reported that the female – male ratio of synaesthetes is as high as 6: 1 and the families of synaesthetes contain more female than male members. This raises the possibility that the gene may be associated with… 
Is synaesthesia a dominantly female trait?
TLDR
A large-scale prevalence study is presented which informs ideas on whether the condition is more prevalent in men or women, and re-analyse previous reports of very large female biases to show again that they likely arose from self-referral or other methodological issues.
Synesthesia in twins: Incomplete concordance in monozygotes suggests extragenic factors
TLDR
The first comparative twin study of CSS is conducted and it is found that CSS has a pairwise concordance of 73.9% in monozygotic twins, and the results suggest a heritable element of synesthesia.
Familial patterns and the origins of individual differences in synaesthesia
TLDR
The findings strongly indicate that various types of synaesthesia are fundamentally related at the genetic level, but that the explicit associations and the individual differences between synaesthetes are influenced by other factors.
Early detection of markers for synaesthesia in childhood populations.
TLDR
This study represents the first assessment of synaesthesia in a randomly sampled childhood population demonstrating the real-time development of the condition and calls for a dialogue between researchers, clinicians and educators to highlight the prevalence and characteristics of this unusual condition.
Synaesthesia and comorbidity
Synaesthesia is a hereditary, neurological condition in which common stimuli trigger unexpected secondary sensations. For example, reading letters may result in the visualisation of colour, a variant
A whole-genome scan and fine-mapping linkage study of auditory-visual synesthesia reveals evidence of linkage to chromosomes 2q24, 5q33, 6p12, and 12p12.
TLDR
The results demonstrate that auditory-visual synesthesia is likely to be an oligogenic disorder subject to multiple modes of inheritance and locus heterogeneity, with important implications for the understanding of the role of genes in human cognition and perception.
Synaesthesia: mechanisms and broader traits
Synaesthesia is a condition in which perceptual or conceptual stimulation in one modality leads to additional experiences within the same or different modality. In grapheme-colour synaesthesia
ynesthesia in twins : Incomplete concordance in monozygotes uggests extragenic factors
Colored-sequence synesthesia (CSS) is a neurological condition in which sequential stimuli such as letters, numbers, or days of the week trigger simultaneous, involuntary color perception. Although
Acquiring synaesthesia: insights from training studies
TLDR
A comprehensive literature review on developmental aspects of synaesthesia and specific training procedures in non-synaesthetes concludes that synaesthetic can potentially be learned by the appropriate training.
Synaesthesia: The Prevalence of Atypical Cross-Modal Experiences
TLDR
The first test of synaesthesia prevalence with sampling that does not rely on self-referral, and which uses objective tests to establish genuineness is presented, and it is suggested that female biases reported earlier likely arose from (or were exaggerated by) sex differences in self-disclosure.
