3. The cell below is currently in Metaphase I. Draw the four resulting cells after the original cellgoes through Meiosis. Write down the genotype above each of the new cells. (ignore crossing over).

You will find the cell in metaphase and the draw of the gametes in the attached files

Gametes: RY, RX, rY, rX

Explanation:

During metaphase I, homologous pairs migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane.

During metaphase II, when the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. This random order in the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get the same genetic charge.

Diploid cell)  RrXY

Gametes)   RY, rY, RX, rX

The alleles of each of the genes randomly migrate to different poles and combine with the allele of the other gene that migrated to the same pole.

it would lead to upper respiratory infections and pneumonia.
