相对应的等位基因。
3.果蝇的红眼(W)对白眼(w)为显性,让红眼果蝇与白眼果蝇 交配,其后代红眼雄果蝇∶白眼雄果蝇∶红眼雌果蝇∶白眼 雌果蝇=1∶1∶1∶1,则亲代中红眼果蝇的基因型是( A.XWXw B.XwXw C.XWY D.XwY )
【解析】选A。果蝇的红眼(W)和白眼(w)基因位于X染色体上。 红眼果蝇与白眼果蝇交配,后代有 4种性状表现,则红眼果
明的,而且通过基因行为与染色体行为的平行关系也得不出 这一结论。
2.下列各项中,能说明基因和染色体行为存在平行关系的是

It may sound strange, but a study suggests this might be true.Two British scientists studied the results of four sports in the 2004 Athens Olympic Games where the athletes had been given either a red or a blue uniform. They discovered that when there was a big difference in the score, color had no influence on the result. But if it was a close match, the athlete in a red uniform was more likely to win. Then they looked at the uniforms of the soccer teams at the Euro 2004 tournament. Again, teams wearing red won more games.The two scientists got their idea from earlier studies of wild animals. It had been discovered that when a male shows red on its body, it sends a signal of its power and strength. For example, in many kinds of monkey, the more the male shows off its red scars, the more females it can attract.Based on this fact, the British scientists thought that the idea might work for humans, too. According to them, when an athlete sees a competitor in a red uniform, he gets a feeling that his competitor could be stronger than him. And that_kind_of_feeling may have a bad influence on the player's performance in the actual game.Although the idea is interesting, most people don't accept that color signals in the animal's world can really be useful to humans in sports. They think that it is unreasonable to develop an idea based on such a small number of examples.Much more research has to be done to prove the influence of uniform colors on the performance of athletes.【语篇解读】科学家研究了2004年雅典奥运会的运动员所穿衣服的颜色,发现当分数差异小时,颜色能影响得分的结果。
