The answer is C) 9:3:3:1
This looks like a dihybrid cross where the expected phenotypic ratio is 9:3:3:1. However, in nature, the numbers cannot be absolut. Let's check it out:
242 purple wrinkled
84 purple smooth
70 yellow wrinkled
24 yellow smooth
Divide all by the smallest number:
242 purple wrinkled / 24
84 purple smooth / 24
70 yellow wrinkled / 24
24 yellow smooth / 24
We have
10.1 purple wrinkled which is near to 9
3.5 purple smooth which is near to 3
2.9 yellow wrinkled which is near to 3
1 yellow smooth
<span>1.) Deletions: A percentage of the chromosome is lost
or removed. </span>
<span>2.) Duplications: A share of the chromosome is
doubled, which results into an extra genetics.</span>
<span>3.) Translocations: A portion of a chromosome
is relocated to an alternative chromosome.</span>
If the stimulus reaches the threshold an action potential will be generated. If the stimulus doesn't reach it no action potential will be generated. If the stimulus will be stronger the action potential will have the same amplitude. The refractory period makes it harder to generate an action potential so they decrease the frequency of action potential production.
If the father had the blood type B then the child would have one of these blood types: AA, AB, AO, BO
None of these blood types is B thus the man is not the father
I’m not sure about the answer but I believe he’s not the father
