Answer:
0.78
Explanation:
Fitness measures the probability of survival and reproduction of a particular phenotype or genotype in a population.
Relative fitness measures how fit one genotype or phenotype is with respect to the most fit genotype or phenotype in a popualtion. It is calculated as = survival rate of that group / maximum survival rate observed in that population
Here,
Total number of yellow birds = 263
Yellows birds that survived = 150
Survival rate of yellow birds = 150/263 = 0.57
Total number of grey birds = 413
Grey birds that survived = 303
Survival rate of grey birds = 303/413 = 0.73
Grey birds have more survival rate than yellow birds so their survival rate is maximum in the population.
Fitness of yellow phenotype relative to grey phenotype = survival rate of yellow birds / survival rate of grey birds
= 0.57 / 0.73
= 0.78
Hence, fitness of the yellow phenotype relative to the grey one is 0.78.
The answer to your question is that the color and specific gravity at the three stages, Tracy might conclude that Max is extremely well hydrated before exercise as the urine is pale and has a low specific gravity,dehydrated after immediately exercise as it is a dark pigment with a high specific gravity and adequately hydrated six hours after exercise as it is a normal pigment and normal specific <span>gravity.</span>
