In a population of ladybugs, a change in DNA of the offspring of one bug produces entirely black bugs. These bugs are more successful in escaping predators. Overtime, this gene becomes more frequent in the population, and the ladybug population loses its red color allele. What type of evolutionary mechanism caused the change in the population?

A. gene flow
B. genetic drift
C. artificial selection
D. mutation

Plz fast biotechnology is a growing field of applied biology. many crops such as corn have been engineered to be resistant to herbicides. therefore farmers can spray these chemicals to kill weeds growing near the crop without worries of killing the crop itself how does this type of biotechnology work? a. by changing the genetic make up of the crops. b. by causing the crops to kill the weeds. c. by changing the type of crops used. d. by changing the location of the crops.
