Evaluate the likelihood function in Exercise 47 at p = 0.09, p = 0.114, and p = 0.1. Where do you think the maximum might be? If you are very determined, it is possible to solve for the maximum.
Color blindness is due to a recessive allele that appears on the X chromosome. If the color blindness allele has frequency p, a fraction p of males will show the phenotype, and a fraction p2 of females will show the phenotype (because they require two copies). We wish to estimate the fraction p from a sample of 1000 males, 90 of whom are color-blind, and 1000 females, 13 of whom are color-blind.
