Ionic bonds involve a cation and an anion. The bond is formed when an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or cation. Another atom, typically a non-metal, is able to acquire the electron(s) to become a negative ion, or anion.
Mainly sons born from mothers to color blind parent(s) would be a trend.
Color blindness usually affects men more than women because the affected X chromosome from their mom is not compensated for with the Y chromosome given to them by their dad. Girls are usually unaffected because the 2 X chromosomes they have overpower the defective gene.
Hope that helps!
