The correct answer is option:
The peak of the bell curve has shifted to the right, with a greater frequency of crickets with long legs and a lower frequency of crickets with short legs.
The given condition would lead the directional selection of the crickets with long legs. Directional selection leads to shifting of curve in one direction, which is more suitable.
The crickets with short leg get easily caught by predators, so, after sometime, there would be a decrease in number of the crickets with short leg. At the same time, the crickets with long leg would manage to save themselves and their number would comparatively increased.
First of all science is needed to study most things including diseases and this is so since the study of diseases would require a research organism of course and this is any creature that scientist would use to study life and so without science this would not be possible as science allows for the study of animals and humans which are likely to be vectors and diseases requires epidemiology which are scientific disciplines similar to biology to better understand the disease processes and so science is definitely needed.
Answer:
A mutation that cause changes to short stretches of nucleotides. These mutations affect the specific genes that provide instructions for various functional molecules, including protein . changes in these molecules can have impact on any number of an organism's physical characteristics
Answer:
Answer is whole-gene or whole-genome.
Explanation:
Genetic variation explains that, no matter how related or identical some organisms might be, there is a or some characters that make them different from one another. These difference is referred to as variation.
Furthermore, whole-gene means the coding and non-coding regions of the DNA>
There are some activities or occurrences that cause genetic variation, these are gene flow, mutation and sexual reproduction.
Examples of genetic variation are color of the eyes, modification of leaf and blood type among others.
