Explanation:
Understanding through into genetic risk factors for various illnesses in the human population come from mouse research. Manipulation of the mouse genome is quite simple, for example, adding or deleting genes to better understand their function in the body.
The majority of mice and rats used throughout medical studies are inbred, which means they are genetically virtually similar, making the outcomes of medical trials more consistent.
Long eyelashes is the dominant trait because, in the last sentence, donna mentioned how nearly everyone in the family had long eyelashes, while barbara and her had short ones. this proves that long eyelashes are much more common in the family than short eyelashes, which means long eyelashes would be dominant, while short eyelashes would be recessive.
Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.
