The purpose of a dichotomous key is to identify organisms
Explanation:
A dichotomous key is a kind of a tool that guides to classify and identify different organisms.
This key as the name indicates - dichotomous- consists of two parts or options to identify a species.
The method utilizes a series of questions/answers with two possible outcomes.
Taxonomically, a dichotomous key is used to basically identify a species or an organism by its scientific name.
All of the natural elements like the plants, animals, birds, etc are identified using this key.
Types of dichotomous key includes nested, linked, branching tree etc.
Answer:
0.0139- frequency of heterozygotes in the population
Explanation:
Let q to the power of 2 represents the frequency of the homozygous recessive (aa) = 1/20000 = 0.00005
This, q = √q^2 = √0.00005 = 0.007
Since p + q = 1
p = 1 - 0.007 = 0.993
Using the formula: p^2 + 2pq + q^2
Where 2pq represents the frequency of the heterozygotes, thing we have
2 x 0.007 x 0.993
= 0.0139
<span>The bottleneck effect is the cause of the sudden shift in the genetic information of the population. Due to the landslide, suddenly high number of the members of the main population died, and this caused genetic drift for reducing the variation in the existing generation, which is now widely different from the original one.</span><span />
