Dafna1 [17]

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.
