果蝇的翅有长翅和残翅两种，眼色有红眼和白眼两种，分别由A、a和B、b两对等位基因控制．甲图为某果蝇的染色体及基因组成，将该果蝇与“另一亲本”杂交，F₁的表现型及其数量关系如乙图，请分析回答：

（1）甲图所示的果蝇体细胞有丝分裂后期移向两极的染色体上的基因组成分别是____ ；减数第一次分裂后期移向两极的染色体上的基因组成分别是____ ；减数第二次分裂后期移向两极的染色体上的基因组成分别是____ ．

（2）分析甲、乙两图可知与该果蝇杂交的另一亲本的基因型为____ ，F₁长翅红眼雌蝇中纯合体占的比例为____ ．

（3）F₁长翅红眼雌雄果蝇自由交配，F₂中残翅白眼雌果蝇所占比例为____ ，残翅白眼雄果蝇所占比例为____ ．

    In Canada you can find dogs, cats, horses etc, in almost every family. These are their pets. People love these pets and pets are their good friends. Before they keep them at their houses, they take them to animal hospitals to give them needles(针) so that they won't carry disease(疾病). They have special animal food shops, though they can get animal food in almost every shop. Some people spend about two hundred Canadian dollars a month on animal food.

    When you visit people's homes, they would be very glad to show you their pets. You will also find almost every family has a bird feeder (喂食器) in their garden. All kinds of birds are welcomed to come and have a good meal. They are free to come and go and nobody can kill any animal in Canada. They have a law to stop people from killing wild(野生的) animals. If you killed an animal, you would be punished(处罚). If an animal happened to get run over(被碾)by a car, people would be very sad about it.

    People in Canada have many reasons to like animals. One of them is: When children grow up, they leave their parents and start their own work and life. Then their parents will feel lonely, but pets can help them. They can be good friends and never leave them alone.
