Document Summary
Phenotype- observed traits genotype- alleles of an individual individual"s behavior or behavioral phenotypic value is based off: genotype, the environment, gene environment interactions. This is called a fixed action pattern (behaviors that are invariant and unlearned). Behavioral differences between wild type and mutant type fruit flies. John paul scott and margaret bastock studied drosophilia melanogaster: direct evidence of a genetic influence on behavior. Bastock studied the behavioral differences between wild type and mutant form. Mutant fly was identified as yellow compared to normal grey color. Why aren"t yellow more common wondered bastock: wondered whether the gene mutation in yellow might induce a behavioral change that resulted in low reprod. Individual genes that are responsible for the majority of phenotypic variation are known as major genes. While those that contribute to small amounts of variation are known as minor genes.
