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.

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.
Well first off, Mendel’s law of segregation states that individuals possess two alleles and a parent passes only one allele to his/her offspring. Mendel’s law of independent assortment states the inheritance of one pair of factors (genes) is independent of the inheritance of the other pair. Now Mendel discovered this through his little experiment with the pea plants that showed certain traits through a particular pattern, subsequently becoming the foundation of modern genetics and heredity.
