Answer:
That is the main difference between sexual and asexual reproduction. Sexual reproduction just means combining genetic material from two parents. Asexual reproduction produces offspring genetically identical to the one parent.
 
        
             
        
        
        
The nervous system and the muscle system respond to stimuli to produce motion. The skeletal movements of muscles are mostly voluntary. 
Involuntary movements occur in these muscles when the nerve impulse passes from a sensory neuron to a motor neuron via an interneuron in the spinal cord. 
<h3>What are Skeletal muscles?</h3>
Skeletal muscles may be defined as the muscles that fasten to your bones and authorize you to achieve a broad range of activities and operations. 
Skeletal muscles control the direct movement of a person's will and are hence referred to as voluntary movement. While the spinal cord is associated with both movements directly or indirectly. It is a prolonged, delicate tubelike network liable for holding incoming and outgoing messages through the brain to the rest body. 
Therefore, it is well described above.

Answer: Cell differentiation is how generic embryonic cells become specialized cells. This occurs through a process called gene expression. Gene expression occurs because of certain signals in your body, both inside and outside of your cells. Cell differentiation occurs during multiple stages of development.
 
        
                    
             
        
        
        
Mendel observed phenotypic traits during the cross of pea plants. Subsequently, he noted each trait had only two forms. 
<h3>Mendel's Experiments</h3>
Mendel crossed pure-breeding pea plants, and then he crossed hybrid generations, as well crossed the hybrid progeny back to parental lines.
From these crosses, Mendel observed the descendence and then formulated a series of inheritance principles.
Mendel noted traits can be divided into dominant and recessive phenotypic characteristics. 
Dominant characteristics were inherited in an unaltered manner after hybridization of true breeding [plants.
