please help with question 4a and b. 

4. The cell below has 2 sets of chromosomes. The larger chromosome bears the allele for wing
size (A or a allele) and the smaller chromosome bears the allele for eye color (R
or r allele).
a
a. Draw all possible Metaphase 1 arrangements that would occur if this cell were
undergoing meiosis. Be sure to label the alleles as shown above!
b. Draw all possible gametes that will result from this cell undergoing meiosis. Again,
be sure to label the alleles.

Expert Answer

Step 1

Cell cycle is a very important process in nature as it is responsible for the growth of organisms and origin of life. During cell cycle, the DNA replicates inside the cell and the cell divides through a series of phases into two daughter cells that are exact copies of their parents. Cell division is the process by which a cell gets divided into two daughter cells. Cell division takes place during the M phase of the cell cycle. There are two types of cell division- Mitosis and Meiosis. Cell division by mitosis gives rise to two daughter cells with equal number of chromosomes as their parents. Cell division by meiosis gives rise to four daughter cells that have only half the number of chromosomes possessed by their parents.
