Stem Colour of Tomato Plants Is Known to Be Under

Essay

Stem colour of tomato plants is known to be under the genetic control of at least one pair of alleles such that A_ results in the production of anthocyanin pigment (purple stem).The recessive genotype aa lacks this pigment and hence is green.The production of two locules (seed chambers)in the tomato fruit is controlled by the dominant allele M,and multiple locules is determined by mm.Determine the genotypic and phenotypic ratios of the F₁ from a cross between an inbred tomato plant with a purple stem and fruit with two locules crossed to a tomato plant with a green stem and fruit with multiple locules.
