A) Crossing over is the mechanism of genetic variation that results from the exchange of gene segments between non-sister chomatids.
Answer:
Explanation:
If there are 5 genes, let us assume that they are in the alternative forms with 2 possible gets for each five... So we have
2 possible gametes for each five = 2 to the power of 5 = 32 gametes
Then genotypes = 3 to the power of 5 = 243
The same also for 10 genes
2 possible gametes for each 10 = 2 to the power of 10 = 1024 gametes
Then genotypes = 3 to the power of 10 = 59,049
The same also for 20 genes
2 possible gametes for each 20 = 2 to the power of 20= 1,048,576
Them genotypes = 3 to the power of 20 = 3,486,784,401
Answer:
C
Explanation:
Nearsightedness is what happens when the image does not reach the retina whereas farsightedness happens when light is focused beyond the retina.
The answer is..<span>The DNA probe binds to the mutated sequence and flags the mutation.</span>
B. specific - meaning it is only able to catalyze a reaction with a certain molecule
