These cells consume bacteria and other pathogens to protect the body from infection. The process begins when chemicals from a pathogen, or damaged tissue, attract a phagocyte. The phagocyte binds to the microbe, envelopes it, and then eats it.
Answer:
The correct option is C. Rare alleles tend to remain rare even when they are dominant.The distribution of a gene among individuals is determined by mating and environmental factors.
Explanation:
Most people believe that a rare allele would only be recessive. But this is not correct. A rare allele can be dominant. The frequency of an allele to occur in a population will depend on the environmental factors. The alleles which code for traits that are best suitable for living in an environment will be seen in more abundance. The frequency of an allele to occur in a population also depends on the breeding trends of the population.
