Segmentation is a squeezing motion of the circular layer of smooth muscle in the small intestine.
<h3>What is segmentation in the small intestine?</h3>
Segmentation, which mostly affects the small intestine, is made up of localized contractions of the Gastro-Intestinal tract's circular muscle. These contractions separate out little portions of the intestine, allowing their contents to move back and forth while being continuously divided, broken up, and mixed.
Our intestines' circular muscles contract during segmentation to churn food back and forth, rather like a washing machine. This churning helps break down food into tiny bits for digestion by allowing it to mix with gastric secretions in the intestines. By bringing chyme into contact with the intestinal walls during segmentation, the technique also helps to increase absorption.

It is because of the different neurotransmitters and their receptors.
Sympathetic stimulation of arterioles in skeletal muscle is mediated by epinephrine acting on its β-adrenergic receptors.
Sympathetic stimulation of vasoconstriction occurs as a result of activation of α-1 adrenergic receptors by norepinephrine released by post-ganglionic sympathetic neurons.

An F1 cross between true breeding brown and white lines is set up. What evidence would best support white fur being dominant to brown -----
The best evidence to show that white fur being dominant is when all the offspring after the cross are white instead of brown
They are therefore expected to produce heterozygous lines.
The evidence that would best support white fur being dominant is when all the lines produced are white despite being heterozygous.
A dominant trait is known to mask the expression of other traits.
