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.

Suppose that in unicorns, two autosomal loci interact to determine the type of tail. One locus controls whether a tail is presen

Nina [5.8K]

Explanation:

As you can see in the picture below, this is a dihybrid cross with a twist.

We can accomplish that mutually parentages are heterozygotes for both characters because the genotypes are

9 unicorns with curly tails (shown in green)

3 with straight tails (shown in red)

3 curly tales trait carriers with no tail (shown in dark blue)

1 straight tail trait carriers with no tail ( shown in light blue)

If this was an ordinary case of the dihybrid cross, we would get a 9:3:3:1 phenotype ratio.

However, since the first trait, the presence of the tail, is affecting the other trait, the trait texture, the ratio is altered.

$\frac{1}{4}$ of the offspring (genotypes tt C_ and tt SS) has no tail, therefore we cannot observe the texture of the tail (some of the tailless individuals have Curly alleles -blue squares marked with green, some of them have Straight alleles -blue square marked with red ).
