Explanation:
Isotopes:
₁₅³¹P and ₁₅³²P
Given parameters:
₁₅³¹P ₁₅³²P
Mass number = 31 32
Atomic number = 15 15
The two atoms are isotopes. Now let us derive numbers of their subatomic particles
₁₅³¹P ₁₅³²P
Protons 15 15
Electrons 15 15
Neutrons (31-15) = 16 (32-15) = 17
Because they are isotopes, they differ in the number of neutrons alone.
Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences in the number of their neutrons.
We clearly see that the mass number and number of neutrons pertaining to the atom differs. This makes them isotopes.

A person can only show a recessive trait if both of their parents carried at least one copy of each of the recessive allele. The parents do not need to show the trait, as one copy is not enough to reveal it, but they must both carry it.
