Individuals that carry a particular allele may have more descendants than other individuals, resulting in the allele becoming more common. Which process causes random alleles to become more common within a population?

gene shuffling

directional selection

natural selection

genetic drift

genetic drift

Explanation:

When genetic drift happens, a random allele becomes more common just by chance. Unlike natural selection, there is no benefit from the random allele that helps the organism to have a better survival rate in genetic drift. It simply coincidence without any cause. Genetic drift will less likely happen if the population bigger compared to a smaller population.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
