Chapter 37, Problem 2Q

Summary Introduction

To analyze:

The evidence based on Table 1 that proves that gigas (gi) mutant is incapable of contributing a mobile floral signal that helps a pea plant in flowering:

Table 1: Gigas allele that is incapable of contributing a mobile signal.

Graft partners (root/stem)	Number of nodes present at first flowering
WT/WT (wild type)	15
gi/gi	Vegetative
gi/WT	17
WT/gi	16

Introduction:

The flowering of a pea plant gets affected by the presence of different alleles. The gigas allele (gi) is the mutant form of the FT gene (flowering locus-T), which helps in the flowering of the plant. The plants with wild type allele take less time to flower. The plants with mutant alleles take longer time to achieve flowering stage.
