  1. Guanine (G) is found at both mutated positions in wild types, while (delG) and adenine (A) respectively, are found when mutations are present. The P-value of genotype classes contrasted with the wild type (GG_GG) is presented as superscript, while the P-value for G(delG)_GG, G(delG)_AG and (delG)(delG)_GG contrasted with GG_AA is given in subscript. The P-values are given only for significant findings (P < 0.05). Solutions are given with the following restrictions; genotype of dam class GG_GG, male, twin and age of dam = 3.
