Explanation:
The ability of any organism in a population to tolerate a chemical like insecticide, pesticide or antibiotic which is designed to kill it or slow its reproduction is called resistance.
For example, the antibiotic resistance is seen in some bacteria like MRSA(Methicillin-resistant staphylococcus aureus). They gain this resistance because they have some variant traits in their genome which provide them resistance against these chemicals.
These individual are selected through natural selection when the environmental condition changes and become adverse. So the correct answer is resistance.

Answer:
1/2
Explanation:
Mendel's law of segregation states that pair of alleles representing a gene segregate during gamete formation and randomly unite during fertilization.
<em>Hence, a gene represented by Rr alleles will segregate into R and r gametes. Out of the two gametes, one will carry R allele while the other one will carry r allele. The probability that a gamete will carry an r allele therefore is 1/2.</em>
