根据短文判断下列句子的正确(T) 与错误(F)。

People's appearance (外貌) depends on things called genes (基因). Genes are found in the cells (细胞) of people's bodies, and they are passed on from parents to children. Here are some facts about eyes.      Many Europeans and Americans can have blue, green or brown eyes. But a brown-eyed person, for example, may also carry genes for another colour in his / her body. So two brown-eyed or green-eyed parents may not have a child with eyes of the same colour. If a child's father and mother both have brown eyes, the child will probably also have brown eyes, but this is not certain.      If one parent has blue eyes and one has brown eyes, their children may have either blue eyes or brown eyes, but most probably will have brown eyes. The gene for blue eyes is recessive (隐性的) and the gene for brown eyes is dominant (显性的). This means that if a child gets a gene for blue eyes and also a gene for brown eyes from. its parents, brown will win, and the child's eyes' will be brown, not blue.

(      )1. Children look like their parents because they get genes from their parents. (      )2. A brown-eyed person only carries the gene for brown eyes in his / her body. (      )3. If a child has brown eyes, its parent may have eyes of other colours. (      )4. If a child's father and mother both have green eyes, the child's eyes must be green. (      )5. If one parent has blue eyes and one has brown eyes, their child mostly has brown eyes.
