In generation one, one parent carries the gene mutation while the other does not. In generation two, all three children are affected by the mutation. What can we conclude about this gene mutation?

- If in generation one, one parent carries the gene mutation while the other does not, but in generation two, all three children are affected by the mutation, it suggests that the gene mutation is likely recessive.
- In a situation where one parent carries the gene mutation (but does not show the trait) and the other parent does not carry the mutation, the mutation might be a recessive trait. If all three children in generation two are affected, it implies that both parents passed on the mutated allele, resulting in all the children expressing the trait associated with that mutation.
