83. LO 83 Explain the difference between 0 heritability and trait not dependent on genetic variationA population may eventually stop responding to artificial selection because:individuals in the population have become homozygous for the alleles responsible for the trait.natural selection opposes any further change in the characteristic.Onatural selection can no longer enhance the results of artificial selection.individuals in the population have become homozygous for the alleles responsible for the trait and natural selection opposes any further change in thecharacteristic.

Artificial selection has done by humans. It is the process of gene alteration due to human activities and new individuals are obtained. Artificial selection has been done to obtain desired traits, such as high-yielding fruits, crops, milk, and meat.Artificial selection is directional as selected and the desired trait obtains. It is different from natural selection. Artificial selection applies to generate genetic changes in the selected organisms. So that the genotype of the organisms becomes heterozygous. Here new and old gene combination gives rise to the new trait. The selection is bidirectional as more productivity occurs on selected species.The result of artificial selection is a heterozygous individual. It is also inherited from generation to generation. At some point, the artificial selection process stops. It happens when the individual in the population becomes homozygous. It is unable to receive new genes. The heterozygous condition would be fatal for them. Another reason is natural selection does not support the altered combination of the organism. Therefore the first option i.e. individuals in the population have become homozygous for the alleles responsible for the traits is the correct answer.
