Thаnk yоu tо Amаndа W. fоr this question! Deep in the ocean, marine biologists discover a rare species of glowing jellyfish that can either pulse with a bright red light or a soft pink glow. This trait is controlled by a single gene, where the dominant allele (R) produces a red glow, and the recessive allele (r) results in a pink glow. The scientists observe a population of 500 jellyfish and 180 of them exhibit the pink glow. What is the observed frequency of the "R" allele? Please answer in decimal format and round to the nearest tenth (one decimal place).
