Steps in determining gene order in a three-point cross 

Identify the non-recombinant progeny

Identify the double-crossover progeny

Compare the phenotypes of double-crossover progeny with the phenotypes of non- recombinant progeny

The characteristic that differs between the double crossover and the non-recombinant progeny is encoded by the middle gene

A brief pulse of red light will induce a response, provided that the light is sufficiently bright, and conversely, very dim light will work if the irradiation time is long enough. 

This reciprocal relationship between fluence rate and time is known as the law of reciprocity

1. The dispersion pattern starts out random but ends up uniform.
2. Uniform dispersions may also result from social interactions.
3. Territoriality between animals also causes uniform dispersion patterns.
