After a hurricane, a small group of seabirds flew off course and formed a new population. the allele frequencies in this new seabird population are different from the frequencies in the original population. what mechanism of evolution caused this change? a. natural selection b. sexual selection c. genetic drift d. mutation

Option C, Genetic drift

Explanation:

Separation of a part of a population from the main population group there by causing reduction of allele frequency is known as founder effect and founder effect is a form of genetic drift.  

For example -

A small island has a a species of plant that has red and white color flowers. Some how the plants producing white flowers got removed from the island and hence  plants now only produce red flower. This incidents must have reduced the allele frequencies of both red and white flower.

Thus, option C is correct

after making a punnet square using bv bv bv bv you will find that the ratio will be 9: 7 or a 128.6% probability.

hope this

the question isn't complete here so i can't right an answer '_'
