In the gene pool of population with 350 individuals a fixed allele has a frequency of 1(one). Fixed alleles is the alleles that is the only variant that exist for that gene in all population.The frequency of gene pool with a population of 350 is = 1 since the frequency of total alleles =1
Virulence factors of virus aids in its ability to infect cells.
Explanation:
Virulence factors help pathogenic microbes to infect host cells by virulence mechanisms – invade host, cause and spread disease, evade the defense or immune mechanism of the host. These factors makes the virus to grow, replicate, and modify the host cells due to its toxicity.
Viruses binds to the receptor protein of the host cell.
Different types of virulent factors are: invasion factors, adhesive or adherent factors, capsules, endo and exotoxins, etc.
The virulence factors decides the severity and rate of spread of an infection
