- Aav AaBbCc Normal No Spacing Heading 1 Paragraph Styles In man, two abnormal conditions, cataracts (C) in the eyes and excessive fragility (F) in the bones, seem to depend on separate dominant genes located on different chromosomes. Normal vision and normal bones are recessive traits. A man with cataracts and nomal bones, whose father had normal eyes, married a woman free from cataracts but with fragile bones. Her father had normal bones. 11. What is the genotype of the man with cataracts and nomal bones? What is the genotype of the woman with normal vision and fragile bones? What type of offspring might this couple expect?

In humans, the inheritance of sickle cell anemia/trait is deter- mined by a single pair of alleles that exhibit incomplete domi- nance. Individuals homozygous for the sickling gene (s) have sickle cell anemia. In double dose (ss), the sickling gene causes production of a very abnormal hemoglobin, which crystallizes and becomes sharp and spiky under conditions of oxygen deficit. Heterozygous individuals (Ss) have the sickle cell trait; they make both normal and sickling hemoglobin. Usually these individuals are healthy, but prolonged decreases in blood oxygen levels can lead to a sickle cell crisis. Individuals with the genotype SS form normal hemoglobin. Work out the following crosses: a. Parental genotypes: SS × SS % of each genotype: 41 % of each phenotype: b. Parental genotypes: ss X Ss % of each genotype: % of each phenotype:Sickle cell disease— what is the background of this disorder: include the name of the disorder, any alternate names used, provide a description of the disorder, and the typical age of onset. What is the Type of genetic disorder: explain if and how this disorder is inherited. Explain the genetic causes of the disorder. Is it inherited? Is the disorder a dominant or recessive trait? Which chromosome is affected in this disorder? Is a gene mutated? If so, name the gene that is affected? How is gene expression impacted (is it a particular type of mutation, a case of a misshapen protein, etc.?)
