Answer:
c. Affected fathers have all affected daughters, but no affected sons.
Explanation:
Given that the disease is caused by a dominant allele on X chromosome, an affected father would have a disease allele in the X chromosome that passes along to the male gamete, while the gametes containing a Y chromosome would not have it (since it is X-linked).
During sexual reproduction, the father passes an X chromosome to its daughters (the second X chromosome being contributed by the mother) but an Y chromosome to its sons (the single X chromosome being contributed by the mother).
Indeed, within an affected father's offspring, all his daughters will receive the affected X chromosome from him, while his sons will receive an unaffected Y chromosome (since the disease is X-linked). These males will not inherit the disease, for they will receive an unaffected X chromosome from her mother (which is expected to be healthy since the disease is rare).
Lipids contain more energy that carbohydrates because they contain more carbon to hydrogen bonds to release energy when broken.
<span>A macromolecule is a large molecule. There are four groups of macromolecules: carbohydrates, proteins, nucleic acids and lipids. Lipids consist of glycerol and fatty acids and are constructed from fats, oils, waxes, phospholipids and steroids. A lipid's function is to insulate the body and provide warmth in cold conditions. It can be concluded that a person with very little body fat gets very cold easily and a person with a lot of body fat gets very warm very quickly.<span>
