About six plant families, weather they form monophyletic, paraphyletic, or polyphyletic group and also check that extrafloral nectries is an ancestral or a derived character in each of six families. Concept introduction: Paraphyletic group is the group of organism that includes an ancestor, but not all of its descendants. Polyphyletic group is a group of organism or other evolving organism that has been grouped together, but does not share an immediate common ancestor. Monophyletic group is the group of organism that includes an ancestor and all of its descendants. Extrafloral nectaries nectar is a sugar rich liquid produced by plant in glands called nectaries within the flower, which attracts pollinating animals.

Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible. Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…
