Question

1.) jack and jill are both heterozygous for albinism, arecessice trait. What proportion of their offspring will be albino?what portions will have a heterozygous genotype? 2.) a form of gout is inherited as a recessive trait. in thisdisease, excess uric acid builds up on the blood and is depositedas tiny crystals in the soft tissues of the limbs and around thejoints. this causes very painful swelling somewhat resembling acutearthritis. Joe and Belinda marry. Joe is homozygous normal, andBelinda is heterzygous (a carrier) for the dieseas. a.) how likelyare their children to have hereditary gout? b.) if joe were also acarrier, would half the children develop gout? 3.) white forelock is a dominant trait. two first cousins withwhite forelock marry. assuming they are both heterozygous for it,what is the chance that each of their children will develop a whiteforelock? 1.) jack and jill are both heterozygous for albinism, arecessice trait.

Explanation / Answer

1.) if both hetero then 25% AA 50% Aa 25% aa, for a recessivedisorder you have to be homo recesive, aa, so 25% of the offsrpingwill be albino and 50% will be hetero 2.) 0% of their children will have the disease, 50% will becarriers, hetero Aa. and 50% will be normal, homo dominant AA. Ifjoe was also a carrier then 25% of the children would developgout. 3.) 75% of the children will develop the diesease and 25% willbe normal
