Two parents both have the genotype gg for a genetic disorder caused by a recessive allele. what is the chance that any of their children will inherit the disorder?

100% because all four are recessive. The case would be different if one of the parents were to have the genotype GG or Gg because G is a dominant allele but since all the alleles are recessive, the chance is 100%

100%

Hope this helped!
