Genes located on different chromosomes will be inherited independently of each other. Mendel observed that, when peas with more than one trait were crossed, the progeny did not always match the parents. This is because different traits are inherited independently – this is the principle of independent assortment
The main component of the thick filaments in muscle fibers is myosin protein.
<h3>
What is myosin protein?</h3>
Myosin comes under motor protein, which is best known for muscle contraction.
They are dependent on ATP and are responsible for motility that is actin based.
This protein is found in the muscle cells.
Thus, the correct option is b, myosin.

The chance of getting a red flower if two pink flowered plants are crossed is 25% or ¼.
<h3>WHAT IS INCOMPLETE DOMINANCE?</h3>
Incomplete dominance is a type of inheritance in which two alleles of a gene are neither dominant or recessive, hence, a intermediate phenotype is produced.
According to this question, in snapdragons, petal color is inherited through incomplete dominance with the possible colors being red, white, and pink.
If two pink flowered plants are crossed i.e. Pp × Pp, the genotype of the offsprings that will be produced as follows:
- PP (1) - red flower
- Pp (2) - pink flower
- pp (1) - white flower
Therefore, the chance of getting a red flower if two pink flowered plants are crossed is 25% or ¼.
