Concept explainers

Nutrition and diet

We are involved in several daily activities. These actions need a significant quantity of energy. The food we eat provides this energy. Food is necessary for development, repair, and other living activities since it supplies energy. All of these are part of the living practice known as nutrition. Nutrition is the study of nutrients in food, how the body uses them, and the relationship between diet, health, and disease. Nutritionists employ concepts from molecular biology, biochemistry, and genetics to understand how nutrients affect the human body. Nutrition also looks at how people can use their diet to reduce their risk of disease, as well as what happens when they ingest too much or too little of a nutrient and how allergies emerge.

Question

Q5.1. Which of the following is FALSE?
O If a genetic disease reduces fertility and the allele that causes the disease offers no other
advantage, the allele will likely eventually disappear, due to natural selection.
Natural selection does not favor individuals who are homozygous for the sickle-cell allele, because
these individuals typically die before they are old enough to reproduce.
Individuals who are heterozygous HbAlHbS are protected from malaria, and this is why sickle-cell
disease persists in wetter, mosquito-prone regions in Africa.
O In regions where malaria does not occur, individuals who are heterozygous HbAIHbS have a fitness
advantage over those who are homozygous for the normal hemoglobin allele (HbA).

2. Sickle cell disease is caused by a recessive allele. Individuals with two recessive alleles usually die of sickle cell disease before reaching reproductive age. However, individuals with only one recessive allele show few of the symptoms of the disease. The frequency of the sickle cell gene seems to be highest in populations of central Africa, a region where malaria is common. a) Do heterozygous individuals have a survival advantage over homozygous individuals in this region? Why? b) Do you think the frequency of the sickle cell allele is higher or lower in Canada as compared to Africa? Explain your answer fully.
27. Which of the following statements best explains the prevalence and geographic distribution of sickle cell anemia allele (HbS). The homozygotes for normal hemoglobin protein are always at an advantage in all environments. Homozygous recessive individuals are selected for in malarial environments. Heterozygous individuals are at a selective advantage in malarial environments. Sickle cell anemia is found in high frequencies only among West Africans and their descendants. none of the above.
