The probability of someone being gay is estimated to be around 2-5%. As dizygotic twins share around 50% of their genes, the chance of Dan being gay is not significantly higher than the general population. Therefore, the probability of Dan being gay, given that Ben is gay, is likely to be less than 25%.
