34．请回答下列关于果蝇性状遗传的问题：
Ⅰ．(8分)果蝇的下列性状分别由位于两对常染色体上的两对等位基因控制，分别用A、a和B、b表示．且基因A具有纯合致死效应。巳知黑身残翅果蝇与灰身长翅果蝇交配，Fl为黑身长翅和灰身长翅，比例为l︰l。当F1的黑身长翅果蝇彼此交配时，其后代表现型及比例为：黑身长翅︰黑身残翅︰灰身长翅︰灰身残翅=6︰2︰3︰l。请据此分析回答下列问题：
(1)果蝇这两对相对性状分别中，显性性状分别为 。
(2)F1的黑身长翅果蝇彼此交配产生的后代中致死基因型有 ，占其后代的比例为 。
(3)F2中的黑身残翅果蝇个体测交后代表现型及比例为 。
Ⅱ.(12分)果蝇的灰身对黑身是显性，控制体色的一对基因B、b位于常染色体上；红眼对白眼为显性，控制眼色的一对基因H、h位于X染色体上.让一只灰身红眼雌果蝇与一只黑身红眼雄果蝇杂交，得到的F1有灰身红眼、灰身白眼、黑身红眼、黑身白眼4种表现型，请回答：
⑴写出杂交亲本的基因型：灰身红眼雌果蝇 ，黑身红眼雄果蝇 .
⑵F1雌果蝇的表现型为 ，比例为 .
⑶从F1中选取一只灰身红眼雌果蝇与一只灰身红眼雄果蝇进行交配，获得F2，若F2中只出现灰身红眼和黑身红眼两种表现型，则F1灰身红眼雌果蝇的基因型为 ，灰身红眼雄果蝇的基因型为 ；若F2中出现了黑身白眼的类型，则F1灰身红眼雌果蝇的基因型为 .
