👉Help needed from same-sex Fraternal Twins | $250 gift cards to be won👈
All eligible TRA members aged 18-65 have been invited to participate in the Colour Game study. Researchers need more of our very valuable same-sex, non-identical twins to determine whether the preference for colours, colour combinations, and the decision-making strategies used to reveal these preferences, are determined by genes, experience, or a combination of both.

Go into the running to win a $250 gift card each, if you and your twin participate in this study. Learn more at https://bit.ly/colour-game-study
Check your email for your invitation or email info@twins.org.au for it to be resent.

Research with twins indicates that music enjoyment is not just a learned behaviour or shaped by environment – it may be part of our biological design.
