Question

Which muscular disorder is inherited?
A. Tetany
B. Muscular dystrophy
C. Myasthenia gravis
D. Botulism

Answer 1

Hint:- Muscle is described as a soft tissue that is present in most of the animals. The muscle cells are composed of protein filaments of actin and myosin. These filaments slide over each other and produce a contraction. This will result in the change in the length and shape of the cell.

Complete step-by-step solution:-
Muscular dystrophy is described as the progressive degeneration of skeletal muscle due to genetic disorder. It leads to the weakening and breakdown of the skeletal muscles. In this condition, the abnormal genes interfere with the protein production that is required for healthy muscles.
Muscular dystrophy commonly occurs in boys, especially in childhood. There is no treatment for muscular dystrophy. The medications and therapy can only slow the course of the disease.
On the other side, tetany is the muscular spasm that occurs due to low calcium in the body fluid.
Myasthenia gravis is described as an autoimmune disorder that leads to the paralysis of the skeletal muscles. Botulism is described as a rare and dangerous type of food poisoning, and it is caused by the bacterium Clostridium botulinum.
Thus, the correct option is (B). Muscular dystrophy.

Note:-
The heredity is defined as the passing of traits from parents to their offsprings. The traits can be passed either through sexual reproduction or asexual reproduction.
The features of the mechanism of inheritance are as follows:
- The genes or factors are responsible for controlling the traits of an individual.
- There are different traits or characters which are controlled by specific genes.
- The genes are present in more than two different forms.
- The various forms of genes are represented as either dominant or recessive.
- The genes have a pair of alleles or multiple alleles that can be the same or different.
- The genes present on the genetic material DNA is found on chromosomes.
