Hemophilia is an X linked recessive condition. A woman has a brother who is hemophiliac and while she does not have the condition she has a brother who has the condition. Hemophilia is due to a mutation in a clotting factor. The exon intron structure of a clotting factor gene is shown below. Exons are blue rectangles. You analyze the DNA of the woman and her brother by PCR using primers which bind to the left and right of exon 4. The results of the gel of the PCR products are shown below. The negative end of the gel is at the top, the positive is at the bottom. Based on these results O O O O Exon 1 23 Woman The woman is likely to be homozygous for the disease allele The woman is likely to be homozygous for the non-disease allele The woman can not be genetically related to her "brother" The woman is likely to be heterozygous 5 Brother 6 7 H 8
