Answer: Put a drop of stain on an outer edge of your cover slide. Place a piece of napkin or paper towel against the opposite side of your cover slip, right up against the edge. This will help draw the stain under the cover and across the specimen.
Albinism is a recessive trait characterized by an absence of pigment melanin responsible for skin and hair color. Actually, albinism is caused by a defect in gene for enzyme which synthesizes melanin. The central dogma of molecular biology explains that the sequence of DNA specifies the sequence of mRNA, which, further, specifies codes for the sequence of proteins. Since a gene is a segment of DNA, altered gene will cause altered mRNA which will cause altered protein. Thus, <span>defect in gene for enzyme which synthesizes melanin will cause the absence of melanin and consequently, albinism.</span>

Explanation:
Because baldness is a sex-linked trait.
In other words, men are simply more likely to express the trait for baldness than women are, because they only need one set of genes for baldness, while women need two.
If, for example, for each gene there is a 1/2 chance that the gene will be for baldness and 1/2 that it will not, then men have a 1/2 chance (because 1/2^1 = 1/2) of being bald, while women have a 1/4 chance (because 1/2^2 = 1/4) of being bald.
This is the reason it's called "male-pattern baldness": it is more common in males. However, this does not explain nor rule out the dearth of women with baldness-women can get it too: it's just less common
