Question restatement: Genetically engineered mosquitoes carry a resistance gene linked to a gene drive, and the question asks which cell division process the gene drive biases in.
Option 1: interphase. Interphase is the stage of the cell cycle when the cell grows and copies its DNA before division. A gene drive does not bias the choice of phases during interphase; this option does not describe a division process and thus is incorrect for explaining how gene drives bias inheritance.
Option 2: transposon jumping. Transposons are mobile genetic elements that can move within the genome, but a gene drive is a distinct mechanism designed to bias inheritance through gamete production rather than a random transposition event. While both involve genome dynamics, transposon jumping does not specify a biased inheritance mechanism during a particular cell division.
Option 3: mitosis. Mitosis distributes identical sister chromatids into two daughter cells for somatic cell division, but a heritable gene drive is aimed at sexual reproduction and inheritance through gametes. Biasing mitosis would affect somatic cells, not heritable transmission through offspring, so this option does not explain how a gene drive propagates through a population.
Option 4: meiosis. Meiosis is the cell division process that produces gametes (sperm and eggs) with half the chromosome number. A gene drive is designed to bias inheritance during meiosis so that the resistance gene is transmitted to more than half of the offspring, enabling its rapid spread through the population. This aligns with the purpose of gene drives in population modification strategies.
Option 5: gametogenesis. Gametogenesis refers to the overall process of forming mature gametes, encompassing meiosis and maturation steps. While related to the production of gametes, the specific mechanism by which gene drives bias inheritance occurs during meiosis itself, not merely the broader process of gametogenesis. Therefore, this option is less precise than meiosis for identifying the biased inheritance mechanism.
In summary, the question targets the division process responsible for biased transmission in gene drives. The mechanism is tied to meiosis, the stage where allele transmission to gametes is determined, enabling biased inheritance of the linked resistance gene.
