ecessive, while black spots on wings is dominant.
Population 1 has 50 butterflies, of which 5 are brown-spotted and 45 are black-spotted
Population 2 has 500 butterflies of which 125 are brown-spotted and 375 are black-spotted
Population 3 has 1.250 butterflies, of which 313 are brown-spotted and 937 are black-spotted.
Which population is least susceptible to an alteration of allele frequencies due to an accident?
a. insufficient information
b. they are all the same
c. population 2 and 3
d. population 1
e. population 2
f. population 3
Which population is most likely to be subject to a bottleneck effect?
a. population 3
b. population 2 and 3
c. population 1
d. they are all the same
e. insufficient information
f. population 2
Which population has the highest frequency for the brown allele?
a. population 1

Answer:

Population 3

As there are more number of individuals in this population , allele frequency is least likely to alter because of accident which may involve not many butterflies.

Population 1

Bottle neck effect causes more losses due to genetic drifts on small populations. So population 1 with 50 butterflies is most susceptible.

Population  3

Population 3 has the highest frequency of the brown allele.

Population 1 = 5/45 = 0.11

Population 2 = 125/500 = 0.2500

Population 3 = 313/1250 = 0.2504

Given the number of blood vessels in the retina, why do you suppose that you are not able to see them normally
AysviL [449]

Answer:

You can't see the blood vessels themselves because vision depends on a process that makes it impossible to see things that are stationary with respect to the retina. Light receptors in the retina respond only to changes in light reaching them, not to a steady image.

Have a great day! :D
