A woman had five children with two different men. This group of seven individuals is analyzed with regard to three different STSs:

STS-1 is 146 bp and 122 bp; STS-2 is 102 bp and 88 bp; and STS-3 is 188 bp and 204 bp. The mother is homozygous for all three STSs: STS-1 = 122, STS-2 = 88, and STS-3 = 188. Father 1 is homozygous for STS-1 = 122 and STS-2 = 102, and heterozygous for STS-3 = 188 and 204. Father 2 is heterozygous for STS-1 = 122 and 146, STS-2 = 88 and 102, and homozygous for STS-3 = 204. The five children show the following results:

Which children can you definitely assign to father 1 or father 2?
