Traits are controlled by both persons gene and by environmental factors.

Genetic factors are greatly influenced in formation of character traits like self controlling , decisions making etc.

Environmental factors means the everything that outside of your DNA which control the trait. The environmental factors can influence the trait either alone or in combination with genes.

Drosophila has three linked autosomal genes that determine different traits. These genes are black (b), vestigial (vg), and singed(sn). Each of the three genes has two alleles: a dominant wild type allele, indicated by a "+" (plus) and a recessive mutant allele indicated by a "-" (minus). (These mutant alleles cause dark black spots, short "vestigial" wings, and bent "singed" hairs, respectively, when homozygous). A testcross is conducted between females that all have the same genotype and are triple heterozygotes...
