Answer:
meiosis
Explanation:
Generating an egg cell in female blue jays happens during the process of "meiosis." In this process, the cell divides–which means the parent cell's chromosomes will be reduced to half. This will lead to the production of 4 gamete cells.
Meiosis consists of two stages: Meiosis I and Meiosis II. The second choice (prophase) belongs to both stages. The third choice (fertilization) refers to the fusion of gametes in order to form a zygote, so it's incorrect. The last choice (mitosis) is another type of cell division. It is not part of meiosis.
