1题目某种昆虫长翅(A)对残翅(a)为显性,直翅(B)对弯翅(b)为显性,有刺刚毛(D)对无刺刚毛(d)为显性,控制这3对性状的基因均位于常染色体上。现图3有这种昆虫一个体基因型如图3所示,请回答下列问题。(1)长翅与残翅、直翅与弯翅两对相对性状的遗传是否遵循基因自由组合定律,并说明 1 Title Long wing (A) of an insect is dominant on the remnant wing (a), orthopterous (B) is dominant on the bent wing (b), and the spiny bristles (D) are marked on the non-pierced bristles (d). Sex, the genes that control these three traits are all located on the autosome. Figure 3 shows a single genotype of this insect. As shown in Figure 3, please answer the following questions. (1) Whether the paired relative traits of long wing and remnant wing, orthopteran and winged wing, follow the law of free combination of genes, and explain
