WW, Ww, Ww, ww are the genotype ratio with 1:2:1
The genotype of a living organism represents the genetic code. It controls everything from the regulation of metabolism to the formation of protein, according to the Brooklyn College website. Finding the genotype ratio requires the use of a Punnett square. Reginald Punnett studied genetic in Britain and created the square used to predict the probability that an offspring receives inherited alleles. Upon completing the Punnett square with the alternate forms of genes called alleles, count the occurrences of each combination and determine the genotype ratio.
