that is your veins, if its a scratch than its minor no worries.
The sclera is commonly called the whites of the eye.
The sclerotic is the white part of the eye. The iris is your eye color. The pupil is the black dot.
Cataract(s).
The sclera also known as the white of the eye, maintain the shape of the eye and protects the delicate inner layers of tissue.This tough, fibrous tissue forms the outer layer of the eye, except for the part covered by the cornea. Scler/o means the white of the eye, and it also means hard.
white eye gene is ressecive, so the white eyed male is homocigous. You already knew that. So, wether the male apports either of his chromosome set, he will give the white eye gene in it. Now the heterocigous red eyed fly has the red eye gene (which is dominant), and the white eye gene (which is ressecive). But since the red eye gene is dominant, the fly has red eyes. Now, theorycally half the offspring would have white eyes, and the other half would have red eyes, because the male would always apport a white eye gene, cause he has a pair of white eyes genes; the female has a white eye gene and a red one. So, she will apport white gene half the times and red gene half the times, and half the offspring would be homocigote (white eye), and the other half would be heterocigote (red eye, since the red was dominant). To make it clear, lets call the white gene W, and the red one R. So the male set would be: (W, W) while the female would be (W, R), now combining them in all possibilities we have: (W, W), (W, R), (W, W), (W, R), as you can see, of four 2 are white eyed homocigotes and 2 red eyed heterocigotes. By the way, check that that is exactly what happens in humans about the sex, female being (X, X), and male being (X, Y), and so statistically we should have half the offspring being males and half of it being females. note: that applies only if the fly species is diploid, like humans. If drosophila melanogaster, which is the one you are talking about i think, isn't diploid, then it would be different from the above.
because you are irritating the eye
The sclera (white part) of the eye can become red from any type of irritation.
The white of the eye is called the Sclera.
The white part of the eye is the sclera, the colored part is the Iris, and the 'black dot' (which is actually just a hole reaching the back of the eye) is the pupil
The usual colour of the white rabbit's eye is red.
The conjunctiva of the eye (the white).
There are a number of reasons why a dog would have brown in the white part of their eye. They might have a parasite.
Some times it may be a sign that your pressure is acting up if you have high blood pressure. If it is itching and red, it may be others signs, like sinus infection, pink eye, etc.
The white part of the eye is called the sclera. It is made up of tough connective tissue that helps protect and support the eye. The sclera is white to provide a stark contrast against the colored iris and pupil, which helps with light reflection and vision.
The sclera is part of the eye and is better known as the white part of the eye. The iris is the colored part of the eye. The sclera is actually a membrane that covers the outside of the eye.
It most likely has an eye infection
It would be really hard, but just check the eye color most albinos have a odd eye color like red.
