In single-gene traits, natural selection can lead to which of the following?
ivanzaharov [21]

Answer;

-Allele frequency change

In single-gene traits, natural selection can lead to allele frequency change.

Explanation;

-Allele frequencies can change over time within a single population, and frequently differ between populations. This change is due to four different processes: mutation, selection (natural and artificial), gene flow and genetic drift.

-Random forces lead to genetic drift. Sometimes, there can be random fluctuations in the numbers of alleles in a population. These changes in relative allele frequency, called genetic drift, can either increase or decrease by chance over time.

r-ruslan [8.4K]

Lysozyme is found throughout our bodies in mucous membranes and saliva to protect us from infection. Some bacteria are able to evade this defense by altering their peptidoglycan.

<h3>What are Lysozymes?</h3>

Animals generate the antimicrobial enzyme lysozyme, also known as muramidase or N-acetylmuramide glycanhydrolase, which is a component of the innate immune system. The glycoside hydrolase lysozyme is responsible for breaking down the 1,4-beta-linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues in peptidoglycan, the main building block of gram-positive bacteria. The integrity of the bacterial cell walls is subsequently compromised by this hydrolysis, leading to lysis of the cells.
