Aquаpоrin chаnnel prоteins аre fоund in the plasma membrane of various cell types. Scientists studied the production of aquaporins in the keratinocytes (skin cells) of healthy individuals and found that these proteins play a role in hydration of the skin. Some individuals have a skin disorder that causes the absorption of excess water by the skin of their hands and feet when they are soaked in water. Scientists determined that the keratinocytes of these individuals are characterized by the presence of abnormal aquaporins. Scientists studied a family in which some individuals have this skin disorder and constructed a pedigree (Figure 1). Figure 1 presents a pedigree with three generations. The first generation consists of an affected male and unaffected female. They have the following second generation children: an affected female, two unaffected males, an affected male, and an unaffected female. The second generation affected female has the following third generation children with an unaffected male: two unaffected males and an affected female. One of the second generation unaffected males has the following third generation children with an unaffected female: two unaffected females and an unaffected male. The second generation affected male has the following third generation children with an unaffected female: an affected male and a female of unknown phenotype as indicated by a question mark. The second generation unaffected female does not have any children. The other second generation unaffected male has the following third generation children with an affected female: an unaffected female and an affected male. Figure 1. Pedigree of a human family in which some members have a skin disorder. An individual with an unknown phenotype is marked by a question mark. Based on the pedigree in Figure 1, predict the probability that the individual marked by the "?” will have the skin disorder. Justify your prediction. Explain how specific membrane-bound organelles of the keratinocytes are used to produce, transport, and modify aquaporin polypeptides from mRNA. A scientist claims that the presence of aquaporins in chloroplast membranes supports the endosymbiotic theory. Support the claim with evidence from biological concepts.
