Akey is a sorting device that lists choices between certain observed characteristics. a dichotomous key is the simplest means of identification. the word dichotomy means "cut or split into two parts." hence, a dichotomous key is a two-part or two-choice key. it asks whether a particular organism has one trait or another—either yellow or brown, either large or small, etc. for this project, you will classify different pieces of fruit by responding to dichotomous questions. in the fruit lab below, respond to the questions to the computer identify all the pieces of fruit. after conducting the fruit lab, answer the following questions: what was your identification accuracy? identify at least three types of characteristics that you were asked about as you the computer identify a fruit. how is the fruit lab like a dichotomous key?

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.

explanation:

the correct answer is:

a population changes in response to a change in the environment.
