Estimate, by simulation, the average number of children there would be in a family if all people had children until they had a girl. Do the same if all people had children until they had at least one boy and at least one girl. How many more children would you expect to find under the second scheme than under the first in 100,000 families? (Assume that girls and boys are equally likely.)

A couple decides to have children. Both have the same genotype:
they are fully heterozygous at the following loci: albino (Aa), MN
blood group (L^M L^N), and Rh factor (Rh+/Rh-). The Rh+ allele is
dominant to the Rh- allele. Assuming that the genes encoding these
traits are located on different autosomes, determine the excepted
genotypic and phenotypic of their ratios in their
offspring.
