A man is heterozygous for sickle cell anemia and homozygous dominant for familial hypercholesterolemia. Knowing that these genes
are located on different chromosomes and using the information below, predict his possible sperm. Sickle Cell Anemia A=Normal hemoglobin a=Abnormal hemoglobin (Sickle Cell) B=Familial Hypercholesterolemia (abnormal LDL protein receptor) b=Normal LDL protein receptor)
Because of the law of independent assortment, alleles on different chromosomes sort independently of one another during the formation of sex cells. Because of the law of segregation, alleles of the same gene do not end up in the same sex cell during meiosis.
Marcia is diagnosed with hypermetabolism.
One pathological
cause of hypermetabolism
is thyroid disorder (hyperthyroidism). It could also be caused by
injury or infection in the body. There is no single
treatment for the disorder since it is merely a symptom of an underlying
problem. It could be managed by nutritional
support coupled with pharmacological treatment such as diuretics and regular insulin.
