If the frequency of one of the alleles is close to zero when the simulation starts, if there is no selection, is it likely to persist?

NO, if the frequency is low the alleles is not persisting according to the rule of natural selection.

Explanation:

Directional selection leads to increase over time in the frequency of a favored allele. Among alleles dominance relationship advantageous rate gets fixed. The reason behind it is rare alleles are mostly found in heterozygotes.

By natural selection when it reaches high frequency then recessive mutation can be seen. After reaching on advantageous allele reached at high frequency that time deleterious alleles are very necessarily rare and due to this it is mostly present in heterozygotes

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
