In a monohybrid cross, if the gene for tall (T) plants was incompletely dominant over the gene for short (t) plants, what would
shepuryov [24]
Incomplete dominance is when the dominant allele is not fully dominant over the recessive allele. This results in three phenotype options rather than three. in this case T= tall, t= short and the two combined would be an intermediate height. A punnet square can help you figure this out.
         T     t
T      TT    Tt
t       Tt      tt

In this case you have one genotype that is two tall (TT) alleles. This will present as a tall plant.
The second genotype present is two  short alleles (tt). You have one of these that will result in a short plant.
The third genotype present is one of each (Tt). This will result in an intermediate height plant. This shows up twice in the punnet square.
Based on this you will have 25% tall, 25% short and 50% intermediate.

Antibiotics are only used to kill bacterias or to decrease their reproductive rate by difficulting their growth and reproduction.

Also, some antibiotics might be used o treat infections caused by some fungi and parasites (but not all of them).  

To remember this, you can just think about its name. Anti- means against, biotic- means life. These are substances used to attack certain living beings, such as bacteria. As viruses are not alive cells (they are DNI + proteins), antibiotics have no effect on them.
