6. A cell contains 2 pairs of chromosomes. The first pair consists of a chromosome with the T and G alleles and a chromosome with the t and g alleles. The second pair consists of a chromosome with the I and f alleles and a chromosome with the i and F alleles. At the end of cell division, the following genotypes are present in the gametes: TGIF, TGİF, TGIF, TGİF, tglf, tgif, tgIF, and tgiF. a. Which type of cell division occurred? Mitosis Meiosis or b. Is there evidence of crossing over in prophase I? Yes No Not applicable c. How did you make the above conclusions?
