The petal color of a species of flowers is inherited along Mendelian ratios. A cross of two plants with red flowers produces 1,068 plants with red flowers and 390 plants with yellow flowers.Propose a model to explain the inheritance of red and yellow flowers.Determine the probability of producing a plant with yellow flowers when a heterozygous plant with red flowers is crossed with a homozygous plant with yellow flowers.

Introduction Mendelian Ratios Are Proportions Of Distinct Genotypes In The Offspring Of Parents With Specific Genotype Combinations. The Transmission Of Features Or Information From One Generation Of Persons Or Cells To The Next Is Referred To As Inheritance. A Genotype Is The Set Of Genes That Make Up An Individual. The Concept Can Also Apply To The Two Alleles That Are Inherited For A Specific Gene. A Phenotype Is An Organism's Set Of Observable Features Or Qualities E.g Hair Color, Height, Eye Colour Etc. A Monogenic Trait Is A Characteristic Or Trait That Is Produced By A Single Gene Or A Single Allele. The Phenotypic Ratio Of Given Progeny Is: 1068 Red Flowers And 390 Yellow Flowers. This Is Roughly Equivalent To A 3:1 Ratio. So, The Dominant Phenotype = Red = RR Or Rr The Recessive Phenotype = Yellow = rr It Is A Monogenic Trait. Parents Must Be Heterozygous For The Red Color, Parental Cross: Red X Red = Rr X Rr R r R RR Rr r Rr rr Progeny: RR Rr Rr rr Genotypic Ratio = 1:2:1 Phenotypic Ratio = 3:1 Cross Between A Heterozygous Red Flower And Homozygous Yellow Flower: Rr X rr r r R Rr Rr r rr rr Progeny: Rr Rr rr rr Genotypic Ratio = 1:1 Phenotypic Ratio = 1:1.
