A, there are several chromosomes with the same morphology in a cell, and there are several chromosome groups in the cell. There are two chromosomes with the same morphology in the cells shown in the two pictures, so there are two chromosome groups, a is correct;

B, the number of chromatids of the cells shown in the two pictures is 8 and 0, respectively, and B is wrong;

C, if the cell division shown in Figure 2 is mitosis and there are no homologous chromosomes in the cell, then the cell is haploid mitosis, which should come from the drone, and C is correct;

D. In Figure L, the cytoplasm of the cell divides unevenly, and the larger side divides to form an egg cell, so the genotype of the egg cell is ad, so the egg cell formed after cell division in Figure L cannot develop the male peak of the AD genotype, and D is wrong.

So: AC.
