The process by which <em>two species evolve</em> as a <em>response</em> to <em>changes in one another over time</em> is called, "coevolution" thus the correct answer is that it is an example of <u><em>COEVOLUTION</em></u>
Answer:
Option (D).
Explanation:
Dolly was the first sheep cloned in the year 1997. The sheep has been cloned from the adult somatic cells. The sheep was cloned by Keith Campbell, Ian Wilmut.
The adult's cell nucleus was fused with the enucleated sheep egg. The egg was then incubated in the surrogate female. The telomeres of Dolly sheep was found to be shorter than the normal individuals.
Thus, the correct answer is option (D).
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.
