Which of the following statements best explains why dominant alleles that cause lethal disorders are less common than recessive

alleles that cause lethal disorders?
Which of the following statements best explains why dominant alleles that cause lethal disorders are less common than recessive alleles that cause lethal disorders?
Most individuals carrying a lethal dominant allele have the disorder and die before they reproduce, whereas individuals carrying a lethal recessive allele are more likely to be healthy and reproduce.
Lethal disorders caused by dominant alleles are usually more severe than lethal disorders caused by recessive alleles.
The presence of a lethal dominant allele causes sterility.
Unlike lethal disorders caused by recessive alleles, lethal disorders caused by dominant alleles usually cause the death of the embryo.

Answer:

The reason why dominant alleles that cause lethal disorders are less common than recessive alleles that cause lethal disorders is that most individuals carrying a lethal dominant allele have the disorder and die before they reproduce, whereas individuals carrying a lethal recessive allele are more likely to be healthy and reproduce (first option).

Explanation:

The severity with which a lethal disorder occurs will determine whether or not the individual suffering from it can have offspring.

With respect to genetic disorders that are lethal, when presented as dominant alleles most of the offspring can inherit them and, consequently, prevent reproduction when the disorder is manifest in the individual.

Diseases that are transmitted to the offspring as recessive alleles are more common, because they can be present in the individual without the disease, in the form of a healthy carrier. This ensures that these types of recessive disorders are more common than those linked to dominant alleles.

How can competitive and noncompetitive inhibition be distinguished in terms of KM?
notsponge [240]

Answer:

The correct answer is option c. "The apparent value of KM increases with a competitive inhibitor, while it remains unchanged with a noncompetitive inhibitor".

Explanation:

The KM value in an enzymatic reaction is defined as the substrate concentration at which the half of the enzyme molecules are binding with the substrate. A way to distinguish between a competitive and noncompetitive inhibition is that the apparent value of KM increases with a competitive inhibitor, while it remains unchanged with a noncompetitive inhibitor. A competitive inhibitor would make that a higher concentration of substrate is needed, while a noncompetitive inhibitor does not change KM since the inhibitor binds to a site of the enzyme different from the active site.
