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.
I think from my personal conclusion genders are different because If there was only one gender no new humans or babies could come into the world at all because there wouldn't be any way for them to be created so if we have a boy and girl gender then we can easily make more and more people to come into the world everyday. Hope this helped
