![]() ![]() If an organism has two unlike factors for a characteristic, one may be expressed to the total exclusion of the other.(This statement is also known as Mendel's rule of segregation.) When the gametes are formed, the factors separate and are distributed as units to each gamete.Each is transmitted from generation to generation as a discrete, unchanging unit.The organism inherits these factors from its parents, one from each.In the organism there is a pair of factors that controls the appearance of a given characteristic.The hypothesis he formed based on his observations included the following: ![]() In order to be considered scientific, hypotheses are subject to scientific evaluation and must be falsifiable, which means that they are worded in such a way that they can be proven to be incorrect.Įxample: When Gregor Mendel in 1865 studied the pattern of single trait inheritance of garden peas he formed a hypothesis on the manner of how these traits were inherited. Out how scientific hypotheses, theories and laws describeĪ hypothesis is an idea or proposition that can be tested by observations or experiments, about the natural world. ![]() Only a few scientific facts are natural lawsĪnd many hypotheses are tested to generate a theory. Progression from a hypothesis to a theory using testable, Methods and principles that are well described. Science is a way of making sense of the world, with internally-consistent Instead, as new data become available, previous scientificĮxplanations are revised and improved, or rejected and replaced.
