Differentiate between the chromosome theory of inheritance and the gene chromosome Theory

Biology
1 answer:
Romashka [77]2 years ago
4 0

Answer:

The Chromosomal Theory of inheritance, proposed by Sutton and Boveri, states that chromosomes are the vehicles of genetic heredity. Neither Mendelian genetics nor gene linkage is perfectly accurate; instead, chromosome behavior involves segregation, independent assortment, and occasionally, linkage.

2) Compare the types of neurons that synapse in the posterior, lateral, and anterior gray horns of the spinal cord.
Mama L [17]

Answer:

<h2>Gray matter: the gray matter is arranged intohorns: The posterior horn extends towards the dorsal root, the anterior horn extends towards the ventral horn, and the lateral horn lies between the posterior and anterior horns. </h2>

Explanation:

The posterior horn is associated with the sensory nerve cells, the anterior horn is associated with the somatic motor neuron, and the lateral horn associated with the ANS ( autonomic nervous system).

Posterior horn:

Sensory neurons pass through the dorsal root ganglion after that the dorsal root and in the gray matter the neurons synapse to inter neurons in the posterior horn or may continue to the white matter and  then enter the spinal cord.

Anterior horn:

The motor portion of the nervous system has two parts; i) the somatic motor system and the ii) autonomic nervous system. The somatic motor neuron stimulates the skeletal muscle with stimulation. The somatic motor neuron cell bodies (part of verve cell) are in the anterior horn of the gray matter.

Lateral horn:  

The autonomic motor neuron send stimulation to smooth muscle, cardiac muscle, and glands etc. The cell bodies( part of nerve cell) of the autonomic motor neuron are in the lateral horn of the gray matter.
