Explanation:
Example, during blood clotting, a cascade of enzymic proteins acitvates each other, leading to the formation of fibrin clot that prevents further blood loss.
Complete question:
Thinking creatively about evolutionary mechanisms, identify at least
two schemes that could generate allelic polymorphism in a population except natural selection that favors heterozygotes.
<u>Select the two correct answers.</u>
-inbreeding among individuals in the population
-purifying selection against mutational variants of alleles in the population
-continuous migration of individuals with new alleles into the population
-mutations that do not severely affect viability and reproductivity
-genetic drift of alleles common in the population
-events leading to genetic bottleneck effect
Answer:
The two events that might favor heterozygotes among the options are
- The Continuous migration of individuals with new alleles into the population
- Mutations that do not severely affect viability and reproductivity. These might favor heterozygous frequencies.
Explanation:
Due to technical problems, you will find the complete explanation in the attached files.
There are several types of microscopes: compound microscopes 0 the most commonly used microscope, uses light illumination and the image that is seen is two dimensional, stereoscope- uses light illumination and the image that appears is 3 dimensional, confocal microscope - uses laser light ,scanning electron microscope - uses electron illumination.
