Clutch size in birds refers to the number of eggs laid in a single nesting attempt by a nesting pair of birds while number in brood refers to the number of young hatched. The graphs below represent the relationship between these parameters (clutch size and number in brood) and fitness in bird populations of the Great tit. The Y-axes for graphs I and II could respectively be
