What are one thing that must happen for evolution to occur according to evolutionary theory?
1-individuals must be able to increase 2- genetic variation 3-must compete for limited resources 4-organisms that can survive in the environment increase

Evolution occurs at the population level

Who solved the problem of how evolution occurs, and what principle did they formulate?
Godfrey Hardy and Wilhelm Weinberg, Hardy-Weinberg principle
According to the Hardy-Weinberg principle, what happens to allelic frequencies in a population if no external forces act upon them?
Allelic frequencies will remain constant, and the population will be in genetic equilibrium.
what is one of the five conditions for a population to remain in Hardy-Weinberg equilibrium?
population is very large , no immigration or emigration , random mating , no mutations , no natural selection
How is the total number of alleles in a population calculated?
total number of alleles in a population is calculated by summing all the alleles from homozygous dominant, homozygous recessive, and heterozygous individuals.

What can cause changes in allele frequencies in a population?
Changes in allele frequencies can occur due to factors like mutations, natural selection, genetic drift, or non-random mating.
