Assume that there are only two alleles at a given locus in a population, and the population is in h-w equilibrium. if the frequency of one allele is 0.6, what is the frequency of heterozygotes in the populationa. -0.6.
b. 0
c. 0.4
d. 0.6
e. 1

Frequency of heterozygotes in the population is 0.4.

C. 0.4

Explanation:

If a population is in Hardy-Weinberg equilibrium, the sum of the frequencies of the two alleles will be equal to 1.  The letter p denotes the frequency of the first allele and the letter q denotes the frequency of the second allele.  

p+q=1

In the problem it is given that p=0.6

p+q=1

0.6+q =1  

q= 1-0.6

=0.4

We have to calculate the frequency of heterozygotes in the population. it is given by the equation

Number of heterozygous individuals =2pq

=

=0.48~0.4

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
