As shown in the figure, in the cuboid abcd-efgh, ab = 8cm, BC = 6cm, BF = 5cm, find the sum of the areas of all planes perpendicular to the edge DC In a cuboid abcd-efgh, the edges perpendicular to dcgf and intersecting with edge AB are In the rectangle abcd-efgh, the edges are perpendicular to efgh and different from edge BC

A. From the perspective of chromosome, the fruit fly can only form one kind of gamete: according to the recombination and free combination of genes, so it is not right,
B. The shape controlled by E gene has the same probability in male and female individuals: because there is only one E gene and there is no allele, it is basically identified as sex chromosome; for recessive genes on sex chromosome, the male has a higher proportion of traits
C. When gametes are formed, genes A.A and B.B are free combination: AB is in the same staining at the same time, so it is linkage exchange, not free combination
