A chromosome of genotype C D recombines with a homolog of genotype c d during meiosis when Spo11 produces a double-strand break between the two loci.If anticrossover helicase disentangles the invading strand, the likely outcome would be
A)two C D and two c d gametes.
B)two C d and two c D gametes.
C)one C D, one C d, one c D, and one c d gamete.
D)four C D gametes.
E)four c d gametes
