Summary Introduction
Introduction:
There are a variety of organisms present in nature. A group of organisms that share certain biological characteristics such as capability of interbreeding with each other is called species. All types of organisms can reproduce and give rise to their offspring. This offspring matures and reproduces to form the next generation organisms. It is an important process to maintain the existence of a particular type of species.

Which of the following is a good description of Sympatric speciation?
A. Speciation without geographic isolation
B. Changes in sequence of DNA of an organism
C. Speciation due to geographical isolation
D. The change in the genetic characteristics of a population of organisms over time
Some species undergo polyploidy, which is a multiplication of their chromosomes. That is, they contain full chromosomes from each parent. How could speciation affect a polyploid organism?
A.
The polyploid organisms may experience gametic isolation.
B.
The polyploid organisms may experience behavioral isolation.
C.
The polyploid organisms may experience geographic isolation.
D.
The polyploid organisms would not be affected by speciation.
Which of the following could result in allopatric speciation?
A.
Two populations of a species are separated by a river that they are unable to cross.
B.
Two populations of a species are separated by a field that is too dry during the summertime.
C.
One group within a population mates during the evenings and another during the mornings.
D.
One group within a population develops a new mating ritual that is not recognized by the other.

- A small number of birds arrive on an island from a neighboring larger island. This small population begins to adapt to the new food plants available on the island, and their beaks begin to change. About twice a year, one or two more birds from the neighboring island arrive. What effect do these new arrivals have? A. Their arrival tends to retard adaptation to the new food plants. B. Their arrival speeds the process of speciation. C. Their arrival tends to promote adaptation to the new food plants. D. Their arrival will likely prompt genetic drift. E. Their arrival represents a colonizing event.arrow_forwardIf two mouse populations do not interbreed but are found in the same area, they may form different species due to d. Adaptive radiation c.

- A population of lizards colonizes a region and feeds on small arthropod species. Over time, a small group within the population starts eating different types of worms. Over time, this group develops inherited traits that help them catch, eat, and digest the worms. The two lizard groups share the same habitat but no longer recognize each other’s mating calls. What does this scenario best describe? A. speciation without geographic isolation B. natural selection without speciation C. increased genetic variation without speciation D. decreased genetic variation with geographic isolationarrow_forwardWhich term can most accurately be used to describe evolutionary change that leads to speciation? A. microevolution b. macroevolution c. sexual selection d. natural selection e. reproductive isolationarrow_forwardA mountain range divides a freshwater snail species into two large isolated populations. Erosion eventually lowers the range and brings the two populations together again, but when they mate, the resulting hybrids all produce sterile young. This scenario is an example of: O A. allopatric speciation by vicariance. O B. sympatric speciation. C. parapatric speciation. D. allopatric speciation by peripheral isolation. « » A Moving to another question will save this response. 8:02 AM 11/10/20 a 18 hp 近arrow_forward
