Asmall population of a specific bird species lives on an island in the pacific ocean. all of the birds of this species have a crest of feathers on their heads. the color of the crest can be orange, yellow, or white. an individual's crest color does not effect its chance of survival or its reproductive success. a hurricane hits the island and all of the birds with orange crests are killed, as well as many of the individuals with yellow and white crests. this causes the gene for orange crests to be lost from the population. the loss of the gene coding for an orange crest in the bird population described above is an example of a. gene flow b. genetic drift c. genetic recombination d. natural selection

B. Genetic drift

Explanation:

Genetic drift is the evolutionary process that leads to changes in gene frequency in successive generation of a small population due to chance alone. It does not include natural selection or gene transfer. In the given example, a change event (hurricane) killed most of the birds with orange crest leading to removal of allele for the same from gene pool. So, it is an example of genetic drift.

a adaptation is when organism changes itself to fit the environment

ex. when its cold outside i wear a jacket

hello everyone my name is nevaeh, i know everyone needs in some way, shape, or form and i am willing to provide. i set up a google classroom where people can ask me questions and get on work. no question is a stupid question so do not be afraid to ask. i usually only focus on core subjects but if you ask i will with other specialized subjects. i can do essays all the way to power points : )

my google classroom is the code is 7hr2k4

~ use this opportunity to get more so you can thrive in the classroom

eukarya because is is like alche and b is bacteria and d is animals
