Answer: Haploid cells contain a single set of chromosomes while diploid cells contain two sets of chromosomes. Haploid cells have half the number of chromosomes as in the parent cell while diploid cells contain the same number of chromosomes as the parent cell.

Explanation: Diploid cells contain two sets of chromosomes while haploid cells contain one set of chromosomes. Diploid cells undergo mitosis while haploid cells undergo meiosis. Diploid cells produces two daughter cells in mitosis while haploid cells produce four daughter cells in meiosis. Diploid cells have (2n) number of chromosomes while haploid cells have (n) number of chromosomes. Diploid cells are somatic cells or body cells while haploid cells are sex cells or gametes. Diploid cells are involved in body growth and repair while haploid cells are involved in sexual reproduction.

Select the correct answer from each drop-down menu. Sickle cell disease is passed on from parent to offspring. Sickle cell disea
allsm [11]

Answer: All the statements of the question are correct.

Sickle cell disease is an autosomal recessive disorder that is characterized by formation of defective hemoglobin protein, which results in sickle shaped RBC ( red blood cell).

This disease is caused by mutation in the gene that is responsible for the protein hemoglobin ( which transport oxygen throughout body).

It is inherited by the offspring when both the mutated copy of genes ( one from each parent) are passed to him.

Carriers of the disease exhibit increased resistance to malarial parasites by controlling the level of free haem in the blood ( through enzyme heme oxygenase that produces a toxic carbon monoxide gas). The resistance thus developed, is a mutation.

Therefore, all the statements in the given question are correct.
