The graph below shows the growth rates of populations of bacteria that have evolved for many generations at different culture temperatures (25°C, 30°C, and 35°C). Each population grows over only a limited range of temperatures (its thermal niche), which are bounded by its critical thermal limits. Within this range, growth rate increases with temperature up to a maximal value and then declines rapidly with increasing temperature. Growth rates are known to be the major determinant of fitness for these bacteria.
Which of the following is true concerning the thermal dependence of growth rate between 25°C and 30°C in these populations?

In the multiple allele series that determines coat color in rabbits, c+codes for agouti, cch for chinchilla and ch for Himalayan. Dominance is in the order c+>cch>ch. In a cross of c+/cch X cch/ch, what proportion of progeny will be chinchilla?
