It is observed that continuous inbreeding of animals for 4 - 6 generations produces progeny with reduced fertility and productivity. What measure can be taken to improve fertility and productivity of progeny?

Continued inbreeding usually reduces fertility and causes non productivity. This is called:

0.75 mole of solid A_(4) and 2 moles of gaseous O_(2) are heated in a sealed vessel, completely using up the reactants and producing only one compound. It is found that when the temperature is reduced to the initial temperature, the contents of the vessel exhibit a pressure equal to half the original pressure. What conclusions can be drawn from these data about the product of the reaction?
