Introduction:
Artificial selection is the intentional breeding of plants and animals. Artificial selection provides a model that helps us in understanding the natural selection. Natural selection is the process that results in the survival and reproductive success of individuals.
Answer to Problem 1MCQ
Correct answer:
Artificial selection and natural selection are similar because of both select for specific traits within a population. Therefore, option c. is correct.
Explanation of Solution
Reason for the correct statement:
Option c. is given as “They both select for specific traits within a population”. Both natural and artificial selection refers to the process that determines which genetic traits are passed from one generation to next. During natural selection, species survival and reproduction determine those traits. Whereas in artificial selection humans can control the traits of their interest which will express in the future generation.
Hence, option c. is correct.
Reasons for the incorrect statements:
Option a. is given as “They both rely on human intervention”. Natural selection does not rely on human intervention. In this nature will itself select the fittest species among all the species. Hence, option a. is incorrect.
Option b. is given as “They both work towards a predetermined goal”. Only artificial selection work towards a predetermined goal. Natural selection is based on the theory in which fittest species will survive, so natural selection non-random processes. Hence, option b. is incorrect.
Option d. is given as “They are processes that only affect animals”. Artificial selection and natural selection also occur in plants too. Hence, option d. is incorrect.
Hence, options a., b., and d. are incorrect.
Artificial selection prepares a basis of natural selection. In both, the selection specific traits will be selected within the population.
