Hi... I just completed this assignment but I'm not sure if i did it correctly or not.. can someone review my assignment?
9. Hand- in question: A brown-eyed man whose father was brown-eyed and whose mother was blue-eyed married a woman whose father and mother were both brown-eyed. The couple has a blue-eyed son. For which of the individuals mentioned can you be sure of the genotypes? What are their genotypes? What genotypes are possible for the others?
1 = brown eye man
2 = his father
3 = his mother
4= his wife
5= wife’s father
6 = wife’s mother
7 = brown eyed man’s son
1 = Bb
2 = B? / he can be Bb or BB
3 = bb
4 = b? / she can be bb or Bb
5 = B? / he can be Bb or BB
6 = B?/ she can be Bb or BB
7 = bb
However, one should note that wife’s father and mother, both cannot be BB because the son is blue-eyed meaning that the wife is blue-eyed.
