Answer:
Hemophilia is a sex-linked recessive disorder in which a person's blood do not clots and he can bleed to death even after minor injuries because blood will keep running due to a small cut.
It is a recessive trait which means that even if one normal gene is present along with Hemophiliac gene, the person will not have the disease and he will be the carrier.
Question: What will be their children’s possible phenotypes?
If a woman who is a carrier for hemophilia marries a hemophiliac man, their genotypes can be denotes as :
Here H, indicate normal gene and small h indicate defected (hemophilia) gene.
Parents: XHXh X XhY
Offspring: XHXh : XHY: XhXh: XhY
Phenotype of offspring:
XHXh: The child will be daughter and normal (25 % chances)
XHY: The child will be son and normal (25 % chances)
XhXh: The child will be girl and Hemophiliac (25 % chances)
XhY: The child will be son and Hemophiliac (25 % chances)
Hope it helps!
Second thoughts:
I don't think doing anything in the future will be of use, because we should have already done it, and we didn't, so we have to do it now.
And what we should do is:
To find and actually use and apply new energy sources.
To do more (or less, depending on what the problem is).
To clean the mess we have done / recover the gap in the ozone layer /fix the damage that we have caused.
If you're interested:
I don't think protesting (like we're currently doing) will be of help for two simple reasons:
1. - I don't know for sure, but I don't think politicians care, like or pay attention to protests (unless it's something like the Yellow Jackets).
2. - The time we spend protesting is more valuable than we think. We should leave that aside.
Hope it helped,
