<h2>Answer:</h2>
If the crossover results in the pair of the chromosome, in which one contains no mutant allele while others contain two mutant alleles.
<h3>Explanation:</h3>
- The crossing over is the genetic random recombination phenomenon in the meiosis.
- In meiosis two homologous chromosomes randomly exchange their genetic material.
- This genetic exchange can be that much random that any part of one chromosome which is near to other can be exchanged leading to lethal and beneficial mutations.
- In crossing over if one chromosome gets the mutant part of the second chromosome while other chromosome gets the normal genetic material in return. This leads to one normal chromosome and the second chromosome having two mutant alleles.
During an influenza outbreak, many people get infected and die. However, part of the population acquires immunity and survives. This is due to variations in the genotype and phenotype among individuals in the population. Probably a particular phenotype confers resistance to influenza. Therefore, this population is able to grow and develop to maturity and reproduce. Their genes are therefore passed over to subsequent generations.
The statement 'resistant insects are able to survive and create a population that is also resistant' describes why the pesticide becomes ineffective.
<h3>What is evolution?</h3>
Evolution is the change process by which individuals adapt to their particular environmental conditions.
The main process by which evolution occurs is called the natural selection of the fittest organisms.
Natural selection refers to the differential survival and reproduction of the most adapted organisms.
