Answer: Incomplete dominance
Explanation: Incomplete dominance is a type of inheritance, specifically a type of intermediate inheritance when a dominant allele, or form of a gene, does not completely mask the effects of a recessive allele, and the organism’s resulting physical appearance shows a blending of both alleles. The result is a phenotype (expression) where the expressed physical trait is a combination of both of the phenotypes that belong to the alleles. One allele doesn’t mask or dominate the other alleles in this instance. It is also called semi-dominance or partial dominance.
In short, incomplete dominance is when neither gene is fully dominant, and the result is a brand new trait.
The Punnett square shows genetic inheritance as a simple model with only two different versions of alleles: dominant and recessive. In this simple relationship, dominant alleles always override the recessive alleles to be expressed in the organism’s appearance or phenotype. It was created by Gregor Mendel and was important because it contradicted popular ideas at the time that the traits of the parents were simply permanently blended within their offspring. However, modern biologists have discovered that inheritance isn’t as simple as this model would suggest.
An example of incomlete dominance in humans would be hypercholesterolemia.
<span>Having
constipation while also having hemorrhoids is a nightmare. You already face
inability passing out poop, yet you still have to brace for intense pain as you
strain to get it out. It is close enough to death by a thousand strains. In
those cases, doctors prescribe stool softeners so the patient can pass out
stools faster and experience lesser pain. Doctors have lots of laxatives to
choose from. The most common one prescribed for hemorrhoids-related
constipation is lactulose. Lactulose is composed of undigestible sugars that
swell once it travels down the large intestine, adding bulk to the stool. It is
preferred because it does not alter function of the intestines.</span>
I believe that secretion into the tubular fluid occurs when the principle cells in the Proximal convoluted tubule secrete H+ into the urine.
Tubular secretion is the transfer of materials from peritubular capillaries to the renal tubular lumen; it is the opposite process of reabsorption. This secretion is caused mainly by active transport and passive diffusion.
Answer:
I am positive the answer is C because I used to study the exact same lesson.
