Male-patterned baldness is more common in males as the name suggest.why is this?
Ray Of Light [21]

Answer:

mark brainliest :))

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
