Answer:
i believe the answer is recessive.
Explanation:
a recessive gene can be expressed as rr instead of RR so if one does a punnet square it would show up to be Rr Rr Rr Rr, since R represents a dominant trait and r being being recessive, then the answer would be recessive. (sorry if it doesn't really make any sense)

Preventing some illnesses, fitness level and what things we do can do to us I think
In 1929 the American astronomer Edwin Hubble discovered that the distances to far-away galaxies were proportional to their redshifts. Redshift occurs when a light source moves away from its observer: the light's apparent wavelength is stretched via the Doppler effect towards the red part of the spectrum. Hubble’s observation implied that distant galaxies were moving away from us, as the furthest galaxies had the fastest apparent velocities. If galaxies are moving away from us, reasoned Hubble, then at some time in the past, they must have been clustered close together.
