Question

a powerful storm dislodged vegetation rafts containing a few impatiens plants, dispersing them to a nearby island. soon after the plants were established, all three flower colors were seen. however, 20 generations later, only impatiens with white flowers were found on the small island. during the next decade several hurricanes in the area caused more plants of this impatiens species to be dispersed to the same small island, after which all three flower colors were seen there again. unfortunately, two years later a volcano erupted, wiping out 99% of the impatiens population on the island. sequence these processes in the order in which they occurred in the scenario.

Answer 1

When a population is drastically reduced in number from the main population to establish a colony, significant impacts dominant allele. The allele population brought on by a population.

The graph displays the dominant allele that is undergoing genetic drift, in which the frequency fluctuates or simply decreases until it is gone. The frequency of the dominant allele increases after the entry of additional population carrying the dominant allele, albeit it doesn't always reach or stop at 50%. To see homozygous dominant (red) and heterozygous (pink) flowers population , the dominant allele's frequency must be high enough.
