You have spent time working with a population of beetles. males range in size from 2 to 6 cm in body length. you realize that the females only mate with males that measure less than 3 cm long. if you measured allele frequencies at a single locus that contributes to overall body length, would you expect this population to be in hardy-weinberg equilibrium for the body length gene from one generation to the next?
select one:
a. yes
b. no

b. No

Explanation:

For a population to be in Hardy-Weinberg equilibrium, it is necessary that the crossings be made completely at random, in the most random way possible. This is not what is happening in the population shown in the question above. This is because if, females only mate with males that are 3 cm long, it means that the crossings are not random, this is occurring preferentially in a specific group of males.

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.
