Question 3 What traits could the student in Question #2 evaluate to get at least partial fitness estimates of her mouse populations given her time limitations? Select ALL choices that apply. - Average daily milk production in mother mice - Number of mice per litter for mothers from each population Yes, this would directly estimate a component of fitness in the parental generation. - Average daily milk consumption of offspring - Survival of offspring through the first week of life. Yes, this would be a direct fitness component. Even if this doesn't provide a complete estimate of survival to the time of first reproduction, it would be part of that calculation. - Average body mass of mice in the parental generation No, this might be correlated with maternal survival or number of offspring, but does not measure either trait. The effects on fitness, if any, might be complex.
