Answer:
6 alleles.
Explanation:
Alleles may be defined as the alternative form of a single gene. The alleles are present on the same chromosome of a particular gene.
CTGT and TGTC are the two alleles of a given gene. Three single crossovers exist between the two alleles. the single crossover can produce two new allele so the three crossovers can produce six new alleles.
Thus, the correct answer is option (D).
Meiosis occur in the nuclear region of the cell, where all the cell's chromosomes are found.
That would be about 150 million years. Hope I helped!
