Artificial selection is different from natural selection because
a. artificial selection is not capable of producing large changes.
b. artificial selection does not require
c. natural selection cannot produce new species.
d. breeders (people) choose which individuals reproduce based on desirability of traits.
Introduction:
The process by which those organisms that have favorable variations to their environment are selected in order to survive and reproduce is known as Natural selection. Artificial selection is the process in which the organisms are selected by the breeder to produce desirable traits in the offspring’s.
Answer to Problem 1U
Correct answer:
The human selects the organism that needs to reproduce on the basis of desirability of the traits through artificial selection. Therefore, option (d) is correct.
Explanation of Solution
Reason for correct statement:
Artificial selection is a man tailored mechanism that mainly occurs in the domestic population. It allows only selected traits to be inherited by the offspring. The result of the artificial selection is predetermined.
Option (d) is given as “breeders (people) choose which individuals reproduce based on desirability of traits”.
As, “in artificial selection breeder select the individual to reproduce on the basis of desired traits,” is the right answer.
Hence, option (d) is correct.
Reasons for the incorrect statements:
Option (a), is given as “artificial selection is not capable of producing large changes”.
Artificial selection tends to bring large changes. Hence, it is a wrong answer.
Option (b), is given as “artificial selection does not require genetic variation”.
The genetic variation is required for the artificial selection to occur. Hence, it is a wrong answer.
Option (c), is given as “natural selection cannot produce new species”.
The process of natural selection leads to the development of new species. Hence, it is a wrong answer.
Hence, options (a), (b), and (c), are incorrect.
The organisms that survive and reproduce are selected by the natural process. Humans select the organisms that need to reproduce with the desirable traits through the process of artificial selection.

- “Gretchen” was a 68-pound canine who came to the VMTH as small animal surgery patient. She receivedacepromazine, 0.2 mg/kg from a 10 mg/ml solution and oxymorphone, 0.08 mg/kg from a 1 mg/ml solution before surgery.What are the mechanisms of action of acepromazine and oxymorphone?

However, a SNP in the position shown in gray (right) would prevent cleavage at this site by EcoRI One of the SNPs in B. rapa is found within the Park14 locus and can be detected by RFLP analysis. The CT polymorphism is found in the intron of the Bra013780 gene found on Chromosome 1. The Park14 allele with the "C" in the SNP has two EcoRI sites and thus is cleaved twice by EcoRI If there is a "T" in that SNP, one of the EcoRI sites is altered, so the Park14 allele with the T in the SNP has only one EcoRI site (Fig. 5-3).

When you sequence this enhancer you find several binding sites for the gap gene, Giant. To test how Giant interacts with eve, you decide to remove all of the Giant binding sites from the eve enhancer. What results do you expect to see with respect to eve expression?arrow_forward
