What species concept should be used in this case?
What species concept should be used in this case? A) Biological species concept should be used in this case, because the apple maggot flies and hawthorn maggot flies are not physical indistinguishable. However, they are genetically distinguishable 2.
What is Morphospecies concept?
The morphological or morphospecies concept is the oldest species concept and uses differences in morphological characters to distinguish species. A biological species is a group of individuals that can interbreed and produce fertile offspring to the exclusion of others.
Why does a biological species have to be reproductively isolated from other organisms?
why does a biological species have to be reproductively isolated from other organisms? reproductive isolation is necessary for lineages to remain distinct through evolutionary time and is responsible for the morphological distinctiveness of species.
Which condition is least likely to lead to geographic isolation and allopatric speciation?
Without any geographical isolation, hummingbirds can continue to interbreed among themselves. The continued interbreeding would not allow their reproductive isolation and thereby would prevent the allopatric speciation.
Which of the following would be considered an example of a Postzygotic isolating mechanism?
Which of the following would be considered an example of a postzygotic isolating mechanism? Answer: e. The failure of a fertilized egg to develop normally is an example of a postzygotic isolating mechanism.
What is the main difference between dispersal and Vicariance?
Dispersal is when a few members of a species move to a new geographical area, and vicariance is when a natural situation arises to physically divide organisms.
Which mode S of selection lead’s to a reduction in variation but no change in the mean?
Stabilizing selection
What are the four processes of natural selection?
Darwin’s process of natural selection has four components.
- Variation. Organisms (within populations) exhibit individual variation in appearance and behavior.
- Inheritance. Some traits are consistently passed on from parent to offspring.
- High rate of population growth.
- Differential survival and reproduction.
