A drawing by Konrad Lorenz showing facial expressions of a dog – a communication behavior. y-axis = fear, x-axis = aggression. Dogs tend to be highly responsive to human cues, especially the direction of a gaze and the direction in which a human points. Dogs rely on the gestures of humans more than verbal cues, most importantly eye contact.
The F2 frequency is higher for [i] because the oral cavity is short and the tongue is at the front of the mouth. The F2 frequency is low in the production of [u] because the mouth is elongated and the lips are rounded while the pharynx is lowered. [5] The IPA vowel chart has the cardinal vowels and is displayed in the form of a trapezium.

Bite inhibition, sometimes referred to as a soft mouth (a term which also has a distinct meaning), is a behavior in carnivorans (dogs, cats, [1] etc.) whereby the animal learns to moderate the strength of its bite.

When a dog has wild-type alleles at all three genes, it will have a yellow coat. When the dog has a loss-of-function allele at MC1R, it will have a yellow coat regardless of the genes it carries on the other two genes. Only a dominant black allele at CBD103 will produce a black coat color in dogs possessing wild-type alleles at MC1R and Agouti. [8]
