1. | Flippers of penguins and dolphins are a pair of homologous organs |
2. | Analogous structures are a result of divergent evolution |
3. | Sweet potato and potato is an example of homology |
4. | Homology indicates common ancestry |
I | It states that, provided some pre-conditions are met with, allele frequencies in a population are stable and constant from generation to generation. |
II | Change of frequency of alleles in a population is interpreted as resulting in evolution. |
III | If the change in frequency of alleles in a population occurs by chance, it is called genetic drift. |
IV | In a population at genetic equilibrium if the frequency of recessive allele is 0.3 then about 42% of the population will be heterozygous for the trait. |
V | Natural selection can lead to disruption when more individuals acquire value other than the mean character value. |
