A person may have one gene for normal heamoglobin and one gene for sickle cell haemoglobin. This heterozygous condition is called a. Genome b. Anaemia c. Gene trait d. Sickle cell trait

Sure, here are the step-by-step solutions: Step 1: Define sickle cell trait. \begin{equation} \text{Sickle cell trait is a heterozygous condition in which an organism may have one gene for normal hemoglobin and the other gene for sickle cell hemoglobin.} \end{equation} Step 2: Explain what is meant by heterozygous. \begin{equation} \text{Heterozygous means having two different alleles (or versions) of a gene. In the case of sickle cell trait, the organism has one normal hemoglobin allele and one sickle cell hemoglobin allele.} \end{equation} Step 3: Define hemoglobin. \begin{equation} \text{Hemoglobin is a protein found in red blood cells that carries oxygen from the lungs to the body's tissues and organs.} \end{equation} Step 4: Explain the difference between normal hemoglobin and sickle cell hemoglobin. \begin{equation} \text{Normal hemoglobin is a round, flexible protein that can easily move through blood vessels. Sickle cell hemoglobin, on the other hand, is a rigid, crescent-shaped protein that can get stuck in blood vessels, leading to decreased oxygen flow and potential tissue damage.} \end{equation} Step 5: Describe the inheritance pattern of sickle cell trait. \begin{equation} \text{Sickle cell trait is inherited in an autosomal dominant pattern, meaning that if one parent has the trait, there is a 50% chance of passing it on to each child.} \end{equation} Step 6: Discuss the prevalence of sickle cell trait. \begin{equation} \text{Sickle cell trait is most commonly found in people of African descent, as well as those of Hispanic, Middle Eastern, and Mediterranean descent. In the United States, approximately 1 in 12 African Americans have sickle cell trait.} \end{equation} Step 7: Explain the potential health implications of sickle cell trait. \begin{equation} \text{While individuals with sickle cell trait generally do not have symptoms, they may experience complications under certain circumstances, such as extreme physical exertion, high altitudes, or dehydration. In rare cases, sickle cell trait may increase the risk of blood clots and kidney damage.} \end{equation}
