Answer:
Each granddaughter cell is haploid (n)
Explanation:
Meiosis in the parent cell with a "2n" chromosome number would produce a total of four daughter cells. Each of these daughter cells would have an "n" number of chromosomes as separation of homologous chromosomes to the opposite poles during anaphase-I reduces the chromosome number to half in the daughter cells. Also, the event of crossing over and random segregation of homologous chromosomes makes the daughter cells of meiosis genetically different from each other.
Each of these four cells enters mitosis and forms a total of eight cells. Since mitosis maintains the chromosome number, each of the eight cells would have an "n" number of chromosomes and would be haploid.
When a species go extinct, it's prey often becomes more populous because it has less predators. A new species can affect the population of prey and predators.
