is the idea of reproductive isolation easy to test in the natural enviroment?can we test it in the lab and be completely sure about the validity of our conclusion?
Homework Answers
No, the idea of reproductive isolation easy to test in the
natural enviroment.
Because for natural environment lot of factor will affect the
environment and also we need to wait for long time period to study
that evolution is occuring or not due to reproductive
isolation.
We can able to test in lab. But the validity of our conclusion is some what relate to the environmental factor. In actual environment the factor might be change compare to lab environment so the result might be vary.

Under nearly all circumstances, postzygotic reproductive
isolation cannot evolve under the direct action of natural
selection. Instead, postzygotic isolation evolves as a by-product
of other genetic changes as proto-species diverge. In contrast,
natural selection can directly act to enhance prezygotic
reproductive isolation. Consider two species with overlapping
ranges. If hybrids between the species are less fit than pure
species individuals, females that mated with heterospecific males
would be at a selective disadvantage, because their resulting
offspring had low fitness....

We are working on the wave model of light. The idea that waves can move around on the surface of a swimming pool or a pond is obvious, partly because you can see the surface of water and the waves have large enough wavelength so you can easily see it. We can see light, but the wavelength is very very short, much shorter than our unaided eyes can see. For example, our eyes are most sensitive to green light. Green...

In a chemistry lab-Calorimetry and heat of reaction we used coffee cups and thermometers to measure the heat of reactions of 3 different solutions (also using Hess' Law) 1. KCl + H2O 2. NaOH+HCl 3. Acetic acid + NaOH in all three calculations for q=mc(delta)T, we assumed that the final solutios all had the same density and heat capsity as pure water and in the post lab it asks: Comment on the validity of asuming that the final solutions in...

4. In class, we used both graphical and table methods to develop the idea that we can take a series of secant lines (lines that pass through two points of a function) and use them to approximate a tangent line. While the secant lines give us an approximate change, the tangent line gives us an instantaneous rate of change or the slopel/steepness of a graph at a single point. Do you this method always works? Does every point on every...

What are the common myths about evolution and why are they wrong? Name and describe the three results of natural selection that can create changes in the percentages of alleles in a population? What are the allopatric and the sympatric speciation? Give examples of each. What are the two major types of barriers that result in reproductive isolation? Give several examples of each type that prevents the result of healthy, fertile offspring between two different species. Trace our hominid ancestor...
