Answer:The answer is option A sister chromatids are separated from each other to form gametes.
Explanation:
Meiosis is a type of cell division which produces 4 daughter cells with different genetic material. The ploidy number or set of chromosomes is reduced to half in the newly formed daughter cells.This process usually proceeds in two divisions-meiosis I and meiosis II with four stages in each division which are prophase, metaphase, anaphase and telophase.Sister chromatids separate from each other during anaphase II of meiosis II which produces four haploid gametes from two intermediate cells formed by meiosis I.Thus, sister chromatids are separated from each other to form gametes is the correct answer.
The biggest reason for that her work is a success is because new ideas often develop from unsuccessful experimentation.
The scientific process not only relies on proper experimental methods and determination, but it also is dependent on the failures of the experiments of scientists. When experiments fail, other scientists obtain a guideline of what to do and what not do. This improves their own experiments and helps them move forward.
