Tetraammine Copper (II) Sulphate

F 1 progeny of pea plant bearing violet flowers and snapdragon plant bearing red flowers were selfed to produce their respective F 2 progeny. Compare the phenotype, genotype and pattern of inheritance of their respective F 2 progeny.

The snapdragon flower shows incomplete dominance. If a plant with red coloured flowers (RR) is crossed with a plant with white coloured flower (rr), the F 1 progeny shows (Rr) the plant with pink coloured flowers. Hence, in the condition in which the selfing of the plant bearing red flower, they have RR genotype. Phenotype: All plants are bearing red coloured flowers. Phenotypic ratio: 100% Genotype: RR Genotypic ratio: RR (100%) In pea plants, the violet flower is the dominant trait. Hence, the genotype of violet flower may be homozygous (WW) or heterozygous (Ww). The pattern of inheritance is complete dominance. If the plant with violet flower is homozygous, Phenotypic ratio: All are violet (100%) Genotypic ratio: WW(100%) If the plant with violet flower is heterozygous, Phenotypic ratio: 3:1 (3 violet flowers :1 white flower) Genotypic ratio: 1:2:1 (WW:Ww:ww)
