Imagine that the cell in the figure below is from a bird known as a blue-footed booby.
a. Is this cell undergoing mitosis, meiosis I, or meiosis II? HOW DID YOU DECIDE?
b. What is the diploid number of the organism from which this cell arose?
c. Name the structures being pulled apart by the spindle fibers.
d. Has crossing over occurred in this cell? If so, for which alleles?
e. What combination of alleles (i.e., what genotype) will be found in each of the daughter cells that immediately result from the completion of the cell-division stage shown above?
f. What is the genotype of the individual (or the diploid cell) that gave rise to the cell above?
g. How many genetically distinct or different gametes (with respect to the genes and alleles shown) can an individual with this diploid genotype produce? Please write the genotypes for all possible gametes that this individual could produce.
