狗体细胞内含有39对染色体，狗的毛色深浅与黑色素合成有关。B基因控制真黑色素合成，b基因控制浅黑色素合成，基因型为BB、Bb的狗分别表现为黑色、棕色，基因型为bb的狗表现为黄色。同时，狗的体色还受E、e基因的影响，当E存在时，真黑色素能够正常合成，e基因导致真黑色素不能合成，这两对基因分别位于第12号和第19号染色体上。请回答下列问题：

(1)这两对基因的遗传遵循孟德尔的__________定律。

(2)若有一只黑色狗与一只棕色狗杂交，子代中黑、棕、黄三种颜色的狗都有。则两亲本的基因型为______________、_____________。子代中黄色狗的基因型为______________。

(3)若第(2)小题中的两只狗再次杂交，生出一只黑色狗的概率是________，这只狗是纯合子的概率为________。

(4)狗的长毛(D)对短毛(d)为完全显性，现有健康成年纯种的黑色短毛雌狗(BBdd)、黄色长毛雄狗(bbDD)各若干只，请通过杂交实验确定D、d和B、b两对基因是否都位于第12号染色体上。请补充下面实验内容。

实验步骤：

①．亲本：黑色短毛雌狗×黄色长毛雄狗→F₁，表现型为________。

②．F₁发育至成年，从F1中选取多对健康的雌雄狗杂交得F₂。

③．统计F₂中狗的毛色和毛长。实验结果分析：若F₂表现型及比例为________________，说明D、d基因不位于第12号染色体上；否则，说明D、d基因位于第12号染色体上。

背景资料

某电气安装工程项目，业主与某电力工程公司签订了工程项目总承包合同。该工程项目的变压器采用自耦式变压器(容量为800kV·A)，电机采用三相异步电动机。
该工程项目的设计单位对变压器的采购编制了采购计划，经业主批准后，由项目经理进行采购。工程监理单位负责对变压器检验的组织工作。变压器运抵施工现场后，进行了开箱验收，经验收合格后，按吊装、吊芯检查、就位、试验、干燥的程序和要求进行安装。变压器安装完毕后，进行了绝缘油的击穿电压试验和交流耐压试验。绝缘油在试验时，温度一直保持在40℃左右，且在清洗注油后即开始加电压试验。变压器安装完成后静止5 h开始进行交流耐压试验。
三相异步电动机在检查过程中经电气试验发现质量可疑。

问题

判断该工程项目的变压器的采购、检验、安装、试验过程有何不妥之处，并改正。
