Is it normal to see better out of one eye?
Yes, it is normal to see slightly better from one eye than the other eye. This is called being "right-eyed" or being "left-eyed", and is much like being right-handed or left-handed. There is no advantage to being one over the other and most people are one or the other.
What if a white eyed fruit fly were crossed with a heterozygous red eyed female fruit fly what ration of genotypes would be expected in offspring?
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.
Is 16 20 better than 20 20 vision?
No, 20/20 vision is considered ideal normal vision where a person can see at 20 feet what a normal person can see at 20 feet. A 16/20 vision means a person can see at 16 feet what a normal person can see at 20 feet, indicating worse vision.
What is a person who can't speak see or hear called?
Deaf A hearing impaired person/ Deaf.
Why are brown eyes more common than other colors?
Because of genes.A Little More InformationThe genes for brown eyes (BB) are dominant.The genes for blue eyes (bb) are recessive.The offspring receive one gene from each parent.In cases where they cross breed the offspring will have brown eyes and their genes will carry the (Bb) blue eye recessive trait.In the case where a brown eyed person with a recessive blue gene (Bb) cross breeds with a brown eyed person with no recessive (BB) all their offspring will be brown eyed, one in four has a chance of having the blue recessive trait. (BB) (BB) (BB) (Bb)In cases where a brown eyed person with a recessive blue gene (Bb) cross breeds with a blue eyed person (bb) two of four of their offspring will be brown eyed with a recessive blue (Bb) and two of four will be blue eyed (bb) (bb)Genetics state that when two people with the recessive trait of blue eyes cross breed they have a 1 in 4 chance of the offspring having blue eyes.(BB) (Bb) (Bb) (bb).As you can see from the above, any time there is a dominant in the mix, that is the colour that appears.
Can a one eyed person watch a 3 d movie?

Why is it harder for a one eyed golfer to see the distance to the pin than it would for a two eyed golfer?
Having two eyes provides depth perception, which is the ability to perceive the distance between objects or the distance to an object. A one-eyed golfer lacks this depth perception, making it harder to accurately judge distances on the golf course, like the distance to the pin.
What colors do rats and rabbits NOT see?
Rabbits are colourblind and do not see the same colours that we do. Rats can see blues and greens but not red at all. Black eyed rats can see one third of the humans can while red eyed rats can see only one thrid of what a black eyes rat sees.
