Somebody needs at least one XC to not be colorblind. XcY doesn't have XC, so they are colorblind. XcXC has XC, so they are not colorblind. (a colorblind female would need both to be colorblind - XcXc)
And XcXC female can pass colorblindless onto her children. For example, even if the father was a normal male (XCY), the one possible child could be XcY (with Xc from the mother and Y from the father), which doesn't have XC so its colorblind.
Answer is chemical energy.
The fuel used in car is petroleum product which is a fossil fuel. Petroleum products such as petrol or diesel are chemical compounds in which chemical energy is stored in their bonds. When these compounds undergo chemical reactions, resulting in breaking of bonds and releasing energy. When ignition of a car is on, the energy is released when chemical bonds are broken. The released energy is carry out work in the car system.
