A farmer plants Bt cotton that is genetically modifed to produce its own insecticide. Of the cotton bolworms feeding on these Bt plants, only 8% survive unless they have at least one copy of the dominant resistance allele R that confers resistance to the Bt insecticide. When the farmer first plants Bt cotton, the frequency of the Rallele in the cotton bolworm population is 0.4. What will the frequency of the resistance allele be after one generation of cotton bolworms fed on Bt cotton? O 0.296 O 0.059 O 0.87 O0.402 O 0.041 O 0.0375

Genetic Variation

Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.

Quantitative Genetics

Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
