Hello everyone, let's see our questions.
00:03
Our question is, describe the markers used to map a phenotype of interest to a region of the genome.
00:11
So here we have to describe a marker.
00:15
And for that, we have four options given.
00:19
Let me read option one by one.
00:22
So option a is they are neutrally varying markers that are volumopic in your population.
00:28
So for this question, option a is the correct.
00:32
Answer that is these are neutrally varying markers that are polymorphic in your population explanation about this that how this option first the first statement i have read is correct let's see so basically according to our question we have to understand the term phenotype first so these are the visible physical characters basically these are visible what we can say observable characters characteristics of organisms like we can say height eye color etc so what are the phenotype visible characters are we can see the height of a person height of organism we can see the color basically here i'm going to mention the eye color so these are some visible characteristics of organism that is the phenotypic nature and polymorphism now let's see the concept of polymorphism what is the meaning of polymorphism so polymorphism means the occurrence of new individual types or characteristic in the same species due to discontinuous genetic variation what it means it means occurrence of new individual why the new individual is occurring.
02:52
So this is occurrence of new individual types.
03:04
Now we can say it as a characteristic in the same species because of the reason for this is the discontinuous genetic covariation.
03:28
So a marker is that shows the polymorphism.
03:32
So this is the marker shows polymorphism or change in characteristics that means synotypic nature.
03:41
So this is a polymorphic marker.
03:46
That's why option a is correct.
03:50
These are neutrally varian markers that are polymorphic in your population.
03:59
Now let's see our option third, option second, third and fourth.
04:04
That means option b, c and d.
04:07
So our option b is they are short tandem repeat sequences...
