Answer:
Gene Frequency = 20% (bb) (Recessive)
Explanation:
Gene frequency in particular population can be found by dividing the known gene frequency by the total number of genes present and then percentage can be calculated by multiplying the whole expression by 100.
Gene Frequency (Recessive) = ( Number Of Genes (Recessive) / Total Number Of Gene Variants In A Population ) x 100
Gene Frequency (Recessive) = (5/25) x 100 = 20%
