Answer:
fixation
Explanation:
Nitrogen is converted from atmosphere nitrogen into usable forms, with the process of fixation
Options have not been provided for the question. They are as follows:
What is the correct order for these genes using a linkage map analysis?
A. Z-X-Y-W
B. X-W-Z-Y
C. W-X-Y-Z
D. Y-W-Z-X
E. Z-X-W-Y
F. Y-X-W-Z
Between which two genes is crossing over most likely to occur?
A. B and D
B.X and Z
C. X and W
D. X and Y
E. W and Z
F. Y and W
G.Y and Z
Answer:
Correct order for these genes using a linkage map analysis: E. Z-X-W-Y
Two genes between which the crossover is most likely to occur: G.Y and Z
Explanation:
According to linkage concept, recombination frequency between two genes = distance between two genes in cM
Here, smallest distance is between X and W ( 7cM ) so they are present next to each other. Distance between X and Y is 17cM and between W and Y is 10cM so W is present between X and Y. Distance between X and Z is 13 cM. Since on one side of X, W and Y are already present Z lies on the other side. So, the final gene order comes out to be, Z-X-W-Y.
According to the gene order, Y and Z genes are farthest from each other. Chances of crossover or recombination increases with increasing distance between genes. So, Y and Z have the highest probability to show crossing over.
Answer:
50% will have long hair!=
Explanation:
When you cross between Hh and hh, two out of four are Hh, which is long hair, and two are hh, which is short hair.
Answer:
Geographical Isolation
Explanation:
Lava serves as geographical barrier to separate the two populations of monkey. These two isolated populations accumulate variations and gradually become reproductively isolated. Reproductive isolation brought about by geographical isolation leads to formation allopatric species which are now present in different geographical regions.
Answer:
Moths make use of several self defending techniques to avoid predators.
Explanation:
Most people often confuse moth with butterflies, but moth are a different member of Lepidoptera, an flying insect. There are many ways through which moth protect themselves from predators.
Since moths are usually active during the night time, so they often hides in the day time from predators. Another technique that moths use is camouflage, where they can confuse the predators by blending into the surrounding. And when a predator us unable to see a moth, its life is saved. Apart from this, moths are even clever enough to trick bats by their strong detection power.
