We know that human has or humans have 46 chromosomes.
00:11
Here, chromosomes denoted by chro, that is 23 pairs of chromosomes.
00:21
So this makes the entire set of chromosomes present in each cell of humans.
00:27
Now, let's consider the given options one by one.
00:30
So the first option that will be negated is the wild type because we know that wild type is just the phenotype of an organism which is as it is as it appears.
00:46
So phenotype is about the external appearance or how the organism appears and not related to chromosomes.
00:55
So this is the rock option.
00:57
The second is triploidy.
01:01
Now triploidy by definition is presence of an extra set of chromosomes.
01:10
So in case of humans, for example, if there are supposed to be 46 chromosomes or let's say 23 pair of chromosomes, there will be 69 chromosomes.
01:25
So this number of 69, this extra set of chromosomes is either derived from mother or father.
01:34
Here mother represented by m and father represented by f.
01:38
According to the image, we can see that there is a presence of 22 pairs of numbered chromosomes in the image.
01:49
So definitely there is no extra set of chromosomes...
