Answer: The frequency of GG is 0.64
Explanation: using Hardy-weinberg equation
g^2 + 2Gg + G^2 =1 ................(1)
And the sum of the alleles at the locus must be 1.
Therefore:
G + g = 1 ..............................(2)
Since
G=0.8
g= 0.2
G^2 =GG (Homozygous G gene)
g^2 = gg (Homozygous g gene)
Using equation 1
GG+ (2×0.8×0.2) + gg =1
Therefore
GG + 0.32 + gg = 1
GG + gg = 0.68...............(3)
Solving equation 2
G + g = 1
g = 1 - G
Square both side
g^2 = (1 - G)^2 ...............4
Where g^2 = gg
Therefore gg = (1 - G)^2.............(5)
Substitute equation 5 into equation 3
GG + (1 - G)^2 = 0.68
Therefore
GG = 0.68 - (1 - G)^2
GG = 0.68 - (1 - 0.8)^2
GG = 0.68 - 0.04
GG = 0.64
Answer:
The <u>biological species concept</u> is not very useful in defining plant species.
Explanation:
The biological species concept says that <em>species are population groups that, in a real or potential way, can reproduce and that </em><em>are reproductively isolated from other groups.</em>
<em>Individuals belonging to a species cannot reproduce with members of other species. </em>
This biological concept has limitations. Its application might present difficulties in concern with asexual reproduction species, such as bacteria, rotifer, cnidarians, plants, and etcetera.
Besides, this concept cannot be applied to the past because it is difficult to deduce reproductive capability between extinct species.
Finally, this concept is not adequate in concern to hybridization zones, something to be expected considering evolutionary processes. This is why this concept has been less accepted by botanists, as some plant species hybridize with other species. For example, species Quercus grisea and Quercus gambelii have overlapping ranges in the southwestern United States. Hybrids showing variation in leaf shape and other traits have been found in many places in this area.
Answer:
false
Explanation:
your body needs a lot on food, materials, etc. from natural resources
Explanation:
But researchers in Israel have done a study showing that families have characteristic facial expressions, ones even shared by blind members of the families. The results suggests that such expressions may be inherited and thus under some genetic control.
A. parasitism. The plasmodium is helped while the human host, harmed.
b. mutualism. The bacteria is supplied with a living environment while the host human is supplied with vitamin K
