The recessive trait, vestigial Wings, occurs in an approximate phenotypic ratio of 1.3. In monohybrid Cross of heterozygous (Rr) parents the expected phenotypic ratio correlates with the given 1:3 result therefore l can conclude that the parents are both heterogeneous (Rr) for vestigial wings. Normal Wings-R, Vestigial Wings (Parent 1) Rr* Rr (Parent 2) R*R- RR- Normal Wings (Child 1) R*r Rr- Normal WIngs (Child 2) r * R - Rr- Normal Wings (Child 3) r*r- rr Vestigial Wings (Child 4) 1 Vestigial Wings: 3 Normal Wings
