In a species of fish, fin shape is controlled by a single gene that has only two alleles. in a generation of 185 fish, the frequency of the recessive allele is 0.25. after six generations, the recessive allele frequency in a population of 230 fish is 0.43. which of the following does this most likely indicate about the dominant and recessive alleles? the dominant allele is more advantageous than the recessive allele because it produces larger populations. the dominant allele will disappear entirely as the recessive allele increases in frequency. the recessive allele is easier to transmit than the dominant allele during reproduction. the recessive allele produces a phenotype that is better able to survive and reproduce than the dominant phenotype.

The correct answer is: The recessive allele produces a phenotype that is better able to survive and reproduce than the dominant phenotype.

Natural selection (adaptation mechanism), gene flow, and mutation combine to change allele frequencies across generations. Natural selection tends to increase in frequency beneficial alleles, while it tends to decrease in frequency deleterious alleles.

The correct answer is D :The recessive allele produces a phenotype that is better able to survive and reproduce than the dominant phenotype.

Explanation:

i took the flvs test and got it correct

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.
