Final answer:
The probability of the parents having a child with a particular genotype depends on their specific genotypes. If both parents are heterozygous for a particular trait, the probability would be 25 percent.
Step-by-step explanation:
The probability of the parents in question #2 having a child with a particular genotype depends on the specific genotype of the parents. Without knowing the genotype of the parents, it is not possible to determine the exact probability. However, if we assume that both parents are heterozygous for a particular trait, then the probability of having a child with the same genotype as the parents would be 25 percent.
