Which of the following best describes what happens to a cell's genetic material during the process of meiosis II?
balandron [24]

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.

Pani-rosa [81]

After the cerebellum receives proprioceptive information from muscles carrying out a voluntary movement, where does it send corrective feedback to primary motor cortex and cerebral nuclei.

The cerebellum, also known as the corticocerebellum, has a close connection to the regulation of movement timing, rate, range, length, direction, and strength. The cerebellum receives information from the command neurons and also obtains feedback (afferent) from the proprioceptive terminals of the muscles, tendons and joints regarding what the actual movements produce .

All these information are combined and the correction signals are given to the motor cortex. The motor nuclei of the cranial nerves and spinal cord exert the lowest level of motor control. Through the closed feedback loop, this occurs.
