<span>Fish and most reptiles rely on their sense of
touch. Some organisms are able to feel the area that surrounds them. They can
feel pressure, detect current, and detect electrical fields within their surroundings, which
help them navigate and ultimately survive and adapt in their harsh environment. Sharks

Answer:
autosomal dominant, affected
Explanation:
Neurofibromatosis is an autosomal (non-sex chromosome) dominant disease, which means that a <u>single mutant gene from the parents can cause the disease in the next generation</u>. And there is a 50% chance of passing the affected genes to the children.
In this case, since we know the mother does not carry the mutant allele, and just one copy of the affected allele is enough for the children to have neurofibromatosis. We can conclude that the father carries the mutant allele and 3 of the 5 children, inherited the afected allele and have the disease.
