How many individuals in the first generation are colorblind?

To determine how many individuals in the first generation are colorblind, you need specific data about that generation, such as the total number of individuals and the prevalence of colorblindness within that population. Colorblindness affects approximately 8% of males and 0.5% of females. If you provide the total number of individuals in the first generation, I can help calculate an estimate based on these prevalence rates.
