Answer:
D. A number of genetically resistant pesticide survivors reproduce. The next generation of insects contains more genes from the survivors than it does from susceptible individuals.
Explanation:
Insect populations already have some insects with pesticide resistance genes. Exposure of insects to pesticides results in the natural selection of these insects with pesticide resistance as they are able to survive and reproduce in the presence of pesticides whereas the other insects die. The resistant insects leave more progeny resulting in the evolution of insect population with increased frequency of pesticide resistance gene.
Answer:
#Genetic variations
#If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation
Explanation:
#That is due to natural selection.
For example:
If both parents are with heterozygous genotype Aa (A is dominant allele for the trait and a is recessive allele for the trait) , than
P: Aa x Aa, the offspring will be
F1: AA Aa Aa aa (one dominant homozygous, one recessive homozygous and two heterozygous.
