Answer:
This suggests that the moustache is a releaser for aggression.
Explanation:
<em>Fixed action patterns</em> are instinctive programmed responses in different species that are triggered by a specific external sensory stimulus. These stimuli are called sign stimuli or releaser. When the sign occurs, the animal starts a sequence of acts in response to the stimulus and continuous until the series of actions is completed.
The black feathers resembling a mustache in a <em>Northern flickers</em> male are an external sensory stimulus. This trait that can provoke another male to respond aggressively, as a f<em>ixed action pattern</em>.
This trait might be considered as an <em>unconditioned stimulus</em>, which <em>provokes an unlearned or reflex reaction</em>. These aggressive responses are triggered by reflex.
I think most scientists would not respect this researchers claim.
It doesn't seem like the researcher followed the steps of the scientific method.
1.) Making an observation.
2.)Asking questions.
3.)Forming a hypothesis.
4.)Conducting an experiment.
5.)Analyzing Data.
6.)Drawing a conclusion.
7.)Showing work to others.
Publishing his/her work would be the very last step after completing everything else.
Answer:
Dominant allele refers to the relationship between two versions of Gene .
Recessive allele is the type of allele that present in its own without affecting the individual .
If you do not have variations to be selected by natural or sexual selection on their superior abilities to survive and reproduce successfully then nothing can be naturally selected against the immediate environment.
