ebayandres Posted October 7, 2009 Share Posted October 7, 2009 (edited) Im taking a genetics class... i was able to figure out the answer but my answer does not match the answer on back of the book. Please help. heres the question 3.15) Albinism in humans is caused by a recessive allele "a". From marriages between people known to be carriers "Aa" and people with the albinism "aa", what proportion of the children would be expected to have albinism? Among three children, what is the chance of one with out albinism and two with albinism? My answer is : 50% would be albinos, and that the chance of having 1 reg and 2 albinos I got 1/8 chance... but the book has 50% would be albinos and that the other is 3/8ths...

Mr Skeptic Posted October 7, 2009 Share Posted October 7, 2009 Your answer is correct for the question "What is the chance that the first child will not be albino and the second and third be albino?" Link to comment Share on other sites More sharing options...
