The proximate significance of the fact that artificial selection can lead to change in a tested population is that it a. demonstrates that the environment has relatively little effect on the development of most behavioral attributes. b. shows that most animal species have a long way to go in reaching their full evolutionary potential. c. shows that populations often possess the potential for evolutionary change in the present, and so they could have been evolving in the past. d. demonstrates that heritable genotypic differences can influence the phenotypic differences observed among individuals in a population.

d. demonstrates that heritable genotypic differences can influence the phenotypic differences observed among individuals in a population

Explanation:

Artificial selection is a process that aims at identifying desirable traits in animals and plants in order to perpetuate them. In artificial selection, breeders choose individuals that exhibit desired phenotypic traits for breeding, thereby shaping evolution by driving genotypic variation. A phenotype can be the result of genetic factors, environmental conditions, as well as a combination of both. In consequence, during artificial selection, higher response to selection may be attributed to a better correlation between a genotype and its phenotype.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
