The effects of neighboring transitions through Doppler broadening on the electromagnetically induced absorption (EIA) and electromagnetically induced transparency (EIT) of the degenerate two-level system (DTLS) in Rb-85 atoms with respect to the linear parallel polarization configuration of coupling and probe lasers have been investigated. The calculated coherent absorption profiles with and without neighboring effects have been compared to elucidate the neighboring effects between the DTLS and nearby states for the conversion between EIA and EIT. Even in the case of the closed system, i.e., F-g=3 -> F-e=4 of Rb-85, for the first time, EIT instead of EIA has been observed owing to the neighboring effect of dominant F-g=3 -> F-e=3 on the linear parallel polarization configuration case of Rb-85 in the low power regime. All the transitions (F-g=3 -> F-e = 2 and 3 and F-g=2 -> F-e = 1, 2, and 3) of linear parallel polarization cases exhibit EIT owing to dominant neighboring EIT in the DTLS. In each polarization scheme, the observed spectral trends of the transitions are similar owing to the neighboring effect. The EIT spectral trends with the neighboring effect of F-g=2 -> F-e = 1, 2, and 3 are governed by the openness of pure DTLS calculation.
