Mendelian genetics one of the fundamental laws is The Law of Independent Assortment. The law states that parental traits are passed independently from parent to child. 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
