In mice the ability to run normally is a dominant trait.  Mice with this trait are called running mice. The recessive trait causes mice to run in circles  only. Mice with this trait are called waltzing mice. Hair color is also inherited in mice. Black hair is dominant over brown hair. Cross a homozygous running heterozygous black mouse with a waltzing brown mouse.  What percentage of the offspring will be waltzing with black hair?

Emotions

Emotions are biologically based psychological conditions caused by neurophysiological changes which are linked to different factors such as thoughts, emotions, behavioral responses, and pleasure or displeasure. These emotions are not similar to moods. The mood is an affective state. Mood depends upon several factors, such as weather, the environment, physiology, etc. Emotions can be beneficial or detrimental depending on the situation. Emotional reactions are simple. Emotional well-being is strongly affected by our well-being, and such feelings are private.
