Short Answer: 1. What are the 5 mechanisms of evolutionary change that make up Modern synthesis?

Solution

Answer = 1]

Five mechanisms of evolutionary change that make up modern synthesis are

1] Natural selection = is the process by which traits that enhance survival & reproduction becomes more common in succesive generations of population

2] Biased mutation =When there are different probabilities occure at molecular level for different mutations to occur known as biased mutation

3] Genetic drift = is the change in allele frequency from one generation to next that occure because alleles are subjected to sampling error

drift acts faster & has more drastic effects in smaller populations

genetic drift contribute to speciation

4] Genetic hitchhiking =When one allele in particular haplotype is strongly beneficial natural selection can drive a selective sweep that will also cause the other allales in haplotype to become more common in population is called as genetic hitchhiking

5] Gene flow = Involves the exchange of genes between populations & species

gene flow between population can introduce traits & alleles
