The color blindness would be from his mother, since it is located in the X chromosome, and since his father is not color blind, and he only has one X chromosome, it could not come from him, but since the trait is recessive in women (meaning that it is covered up by a capital X) it means his mother could have the trait in one of her chromosomes, but not the other. Unfortunately Bob got the short end of the stick and got the chromosome with color blindness, and since men only have one X chromosome, it is dominant in men, leaving Bob with color blindness.
Broad-spectrum antibiotics can cause antibiotic resistance.
Explanation:
Antibiotics are the substances that inhibit the growth of or kill the bacteria and hence, these are used as medications for the treatment of a lot of bacterial diseases.
These antibiotics can either be of broad-spectrum or the narrow spectrum.
The broad-spectrum antibiotics are the ones that are effective against a variety of bacteria, both gram-positive and negative whereas the narrow-spectrum antibiotics are the ones that target only a specific type of bacteria.
Since the bacteria can mutate very fast and hence, develop antibiotic resistance, the doctors usually avoid prescribing broad-spectrum antibiotics and only use them when the causal bacteria is completely unknown.
Hence, in the given case the provider prescribes separate medications for both types of bacteria.
