Hello students, in this question we have been asked several questions.
00:04
The first one is compared to sperm carrying the x chromosome, the sperm carrying y chromosomes are dash.
00:20
So the options given are a lighter, lighter and faster as well as they die quicker and the other options are heavier, faster and die quicker.
00:42
Option c is lighter, swims slower and live longer and option d is heavier, swims slower and live longer.
01:04
So we have to understand one thing that the motion of the sperm is energized by the mitochondria that is present.
01:12
So for the sperm carrying y chromosome we know that the y chromosome is the smallest chromosome, so if a sperm is having y chromosome that means it is going to be lighter than the x chromosome.
01:26
So we can eliminate the other options, let's say that is, let's say that that is heavier, so that is option b and d.
01:35
Now we have two options with lighter, when something is lighter its ability to move becomes faster.
01:44
So the y chromosome will be moving faster than the x chromosome.
01:51
So that, in that sense we can eliminate option c as well because it says that it will move or swim slower.
02:00
Die quicker because it is moving faster, swimming faster, the energy expenditure will also be higher.
02:08
As a result it has the potential to die quicker.
02:12
So the correct answer is option a.
02:19
Next question is, if visually comparing the sexual development of a third week embryo, what will we see with regards to the female and male embryos? so in the third week there is no such development seen for ovaries or testes.
02:45
It is after or for 100 % sure observation you have to look for that after 12 weeks.
02:56
So at the 3 week stage you will not see any development, sexual development.
03:02
So the correct option is option d, no development yet.
03:11
Next question is about a genetically female infant with ambiguous genital, ambiguous genitals could be called what? so based on the options that is transgendered, transgendered, androgynous, intergendered, i'll take it here, intergendered and intersexed.
03:59
Now when you talk about male and female, it is gender that we're talking about, girl and boy, but that is the social construct of girl and boy, girl or a boy...
