You are connecting the original group of all babies with two subgroups of babies. The albinos are in one subgroup, and the nonalbinos are in the second subgroup. Each subgroup must be considered separately from each other and from the original group of all babies. The odds of pulling a heterozygote out of the nonalbino group is 10/15 = 2/3 = approximately 66%. The odds of pulling an albino out of the albino group is 5/5 = 1/1 = 100%. If the odds remained the same in both subgroups as in the original group of all babies, then you'd have to claim that the odds of pulling an albino out of the albino group is 25%.
