Female stalk-eyed flies prefer to mate with males that have longer eye stalks, and the average male eye stalk length is much longer than that of females. This is an example of _______
mutation
macroevolution.
disruptive selection
sexual selection.
2
Several different species of small nocturnal primates called, bush babies live in the woodlands of Africa While several different species of bush babies often live in the same habitat they cannot interbreed because bush babies have genitalia that will only fit the genitalia of females belonging to the exact same species. This is an example of which of the following?
A pre-zygotic barrier
Disruptive selection
A post-zygotic barrier
Sexual selection

Which of the following is a good example of an evolutionary bottleneck?
Two populations of fruit flies are unable to mate because their reproductive organs do not properly fit together.
In 1814, a group of 15 people from Great Britain established a colony on a small island in the Atlantic One of the colonists had a rare genetic disorder that causes vision loss. Two hundred years later, the freque of this vision loss allele is 10 times higher on the island than it is in Great Britain
A tree frog population contained equal ailele frequencies for yellow skin and for green skin until a wildfire randomly killed almost all of the frogs. Now only yellow-skinned frogs are present in this population and green skin allele appears to have been lost.
A tetraploid plant species evolves from a diploid ancestor. Both the tetraploid and diploid species are found in the same habitat.

The Harris's antelope squirrel only lives on the south rim of the Grand Canyon, while the closely related white-tailed antelope squirrel only lives on the norther rim of the Grand Canyon. The presence of the Grand Canyon reproductively Isolates these two similar species from one another. This is an example of _______
1.female stalk eyes flies prefer to mate with males that have longereye stalks. and tbe aberage male eye stalk length is much longer that of female. This is an example of sexual selection.
2.Several different species of small nocturnal primates called bushbabies live in the woodlands of Africa. While several different species of bushbabies often live in the same habitat that cannot interbreed because the genetalia that will only fit the genetalia of female belonging to the same species. This is an example of post zygotic barrier.
3 An example of evolutionary bottle neck is that a tree frog population cobtained equal allele frequency for yellow skin amd for green skin and until a wild fire almost killed all of the frogs. Now only yellow skin frogs are present in the population and green skin allele appears to have been lost.
Female stalk-eyed flies prefer to mate with males that have longer eye stalks
