Biology riddle

Woman has brown hair, brown eyes, is not a hemophiliac, has type A blood.

Her son has blond hair, blue eyes, has hemophilia, is colorblind, type O blood.

Man in question has brown hair, brown eyes, not colorblind, no hemophilia, type B blood.

If brown is dominant and blue eyes/blond hair is recessive, is he the father?Biology riddle
No, I am.Biology riddle

Brilliant
He could be, but you can't prove it either way.
Nice riddle. Too many holes in it.

It's riddled with holes. HAHAHAHA I WIN.
Is this your homework by chance?
if brown hair was dominent then even if both the mom and dad were AB and not AA ( a being brown hair allele) then AB times AB would make 1/4 chance for brown haired kid, but if its dominant, then the kid must have brown hair.. he cannot be the dad, or i have this all mixed up and should read the first couple chapters of my anthropology book again.
This sounds like a homework question to me... >__>
memory lapse, carry on
You'd need to know what the grandparents were. So technically, he is and is not the father.
Never mind, I had a memory lapse
not really complete since we dont know about grandparents and great grand parents

If brown is dominant and blue eyes/blond hair is recessive, is he the father?[/QUOTE]i think its possible but highly unlikely if you check the allelesW: H,h E,e P,p A,OS : h,h e,e p O,OF : H,h E,e P B,Othose are the alleles for them and its highly unlikely that a son will have all receccuve alleles when the parents both have the dominant phenotypeBut in the case of hemophillia and colourblindness, the father is nonimportant as those traits can only be passed on from the mother if the offspring is a male, and b/c the mother dosent have hemophillia it means she was a carrier unless she is not the mother O.O I ignored colourblindness as it is irrelevant.Table of contents: H/h = hair, E/e = eyes P/p = hemophillia, A/O, B/O, O/O = Bloodtypes
I refuse to do your homework for you... :x
[QUOTE=''HybridPhoenix'']you guys are too busy focusing on the last line, hemophilia is the key. Hemophilia is a trait that can';t be dormant in men, if the mom doesn have it and isn't carrying it, and the dad doesn't have it, he's not the father if the son has hemophilia. facts.[/QUOTE]I think you fail to realize Hemophillia is an X linked trait which means its only on the X chromosome. Biology 101 Females have XX gene Types while males gave X,Y types. If the offspring of a couple is a male that means, the mother passed the X(always happens in normal childbirth) and the father passed a Y( due to mieosis sperm only have 23 chromosomes, as do eggs and they carry each only one of the gender genes X or Y) which therefore means that the father has no say in whether or not the son has hemophillia, that means that unless the woman isnt the mother she is a carrier of hemophillia.

Touche, my bad. Can't believe I forgot that. Too busy focusing on the fact that if the guy has it, it can't be dormant, forgot the aspect that it can't be passed on..
