Question

Wild-type Arabidopsis plants produceanthocyanins- a pigment which gives a purplish tinge to theirleaves. Absence of the pigment results in the leaves appearinglight green. Two plants with purplish leaves were crossed, and 1875seeds were produced as a result. When these seeds were germinated, the seedlings were scoredfor leaf colour. 1271 seedlings had purplish leaves and 604seedlings had pale green leaves. What are the genotypes ofthe parental plants, and how did such a segregation arise? Wild-type Arabidopsis plants produceanthocyanins- a pigment which gives a purplish tinge to theirleaves.
