Answer:
2 of the children's feet will be webbed, and the other 2 will have paws.
Step-by-step explanation:
The dominant genes of the Mother will override the recessive genes of the Father, since there isn't 2 of the recessive genes, except for on the other 2 children. If there was a dominant gene, it would have at least 1 capital letter, and that dominant gene would prevent the recessive (lowercase) letter from showing up.
