If a boy has a nearsigghted farther does this mean the boy will come nearsighted? Why or why not?

Answer 1

Many sites tend to support the idea that nearsightedness (myopia) may not be inherited at all, and the ones that think that it is genetic, suggest that both parents have to carry the gene for myopia in order for it to present in their children. Here is one website with information that may be of more help. Good luck to you.

Answer 2

not necessarily. it depends on the mother's vision. if she is nearsighted, then yes, the boy will also be nearsighted. but if the mother is not nearsighted, there is only a 50% chance that the boy will be nearsighted.

Answer 3

It depends on if its genetic or a problem with the environment, like reading with too little light. If its genetic it depends on if its a dominant or recessive gene. If its dominant then theres a 50-50 chance if the mother doesnt have it, and if its recessive and the mother doesn't have it then the boy probably wont get it.

Answer 4

well cant tell depends on the mom and if she is yes if she isnt no well if she is Gg and hes gg then he has 1/4 chance
