A blue eyed man, both of his parents are brown eyed, married a brown eyed woman, whose father was brown eyed and whose mother was blue- eyed. What are the genotypes of everyone in the family? (Brown eyes are dominant to blue)
If a man is blue eyed (bb) then his parents are (Bb and Bb) because if they were BB and Bb, or BB and BB. Then there would not be any blue eye offspring.
And for the woman he married is brown eyed so she must be Bb or BB. Her mother is blue eyed so she is bb and her father is brown eyed so he must be BB and Bb. So how do you know if father is BB or Bb!
and
a right handed, blue eyed man, whose father was left handed, marries a left handed, brown eyed woman whose family members have been brown eyed for several generations.( right and brown are controlled by dominnant genes)
so my knowledge tells me that man is RRbb or Rrbb and his father is rr and man married a girl who is llBb or iiBB
