Huntington's disease is a genetic disorder that is caused by a dominant allele. which of the following is true? a. a child who inherits one copy of the gene that causes huntington's will have the disease. b. a child who inherits one copy of the gene that causes huntington's is a carrier for the disease. c. huntington's disease tends to skip generations. d. a person with huntington's disease will pass the disease on to 100 percent of their children.

A child who inherits one copy of the gene that causes Huntington's will have the disease.

Explanation:

As per given information, Huntington's disease is a dominant genetic disorder. Hence, all the individuals having one or two copies of the causative gene would be affected, that is, the disease is expressed in both homozygous dominant and heterozygous dominant genotype.

So, if a child obtains one copy of the gene for the said disease, the child would be affected by the disease.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
