2/16white: 3/16green: 1/16yellow two genes interact to produce various phenotypic ratios among f2 progeny of a dihybrid cross. design a different pathway explaining each of the f2 ratios below, using hypothetical genes r and t and assuming that the dominant allele at each locus catalyzes a different reaction or performs an action leading to pigment production. the recessive allele at each locus is null (loss-of-function). begin each pathway with a colorless precursor that produces a white or albino phenotype if it is unmodified. the ratios are for f2 progeny produced by crossing wild-type f1 organisms with the genotype rrtt.

the answer is "a.) well–developed vascular system."

explanation:

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
