It was made popular by Francis Galton, but it was first mentioned in John Locke's works
Answer: This situation is an example of directional selection.
Explanation: The graph shows a shift to one particular extreme. Larger body size is being selected over smaller body size.
<span>Genotype is genetic and phenotype is environmental. An organisms genotype is total genome determines its characters. Genome is the total genes for all the characters. Its outcome is called phenotype. It is greatly influenced by the environemental factors. Same genotype may produce different phenotypes in different environments.</span>
Answer:
The effect might be due to the gene expression.
Explanation:
The effect might be due to the variation in the gene expression in the organism. In this way, the variety of the genetic pool is likely to result in a diversity of the gene pool or genome. Because of the mutation and the environmental factors, there is likely to be a slight variation of the species. This results in a slight difference in the phenotypic expression.
