The functions of prop roots, buttress roots, and pneumatophores. Introduction: The underground branching root systems are often more extensive than aerial part of plant. The extension of root depth and spread of a plant differ for another plant species and it also varies among individuals of same species. The modified forms of roots are the adventitious roots that arise from the stem nodes. There are various aerial modified roots that are adapted for functions other than absorption, conduction, anchorage, or storage.

Question

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…
