First, we will elaborate the terms that are being used.
Heterozygous:
This means that the organism has a set of alleles which are different from one another. One copy may be for the dominant trait and the other for the recessive one.
Homozygous:
The organism has two copies of the same allele
Dominant:
An allele that will express itself even if only one copy of it is present. These are usually represented by capital letters.
Recessive:
An allele that requires both copies to be expressed. These are usually represented by lower-case letters.
A: Heterozygous
B: homozygous recessive
C: Homozygous dominant
D: Homozygous recessive
E: Homozygous dominant
An antimicrobial<span> is an agent that kills microorganisms or inhibits their growth. </span>Antimicrobial <span>medicines can be grouped according to the microorganisms they act primarily against. For example, antibiotics are used against bacteria and antifungals are used against fungi.

Selective toxicity<span> refers to the ability of the drug to targets sites that are relative specific to the microorganism responsible for infection. Sometimes these sites are unique to the microorganism or simply more essential to survival of the microorganism than to the host.
Selective theory relates to antimicrobial because the antimicrobial is the drug that kills microorganisms and inhibits there growth, selective theory is the ability of the drug.
