Chapter 40.1, Problem 3LO
Summary Introduction
To identify: The two Arabidopsis mutants that have been used to study phase change.
Introduction: The plants are the multicellular eukaryotic organism in the kingdom Plantae. It is characterised by photosynthetic nutrition, a process through which it synthesis carbohydrates, essential unlimited growth at localised region, presence of cellulose in their cell wall and absence of locomotory organs.

Two morphotypes of the newly discovered plant in Mt. Banahaw de Lucban were tested for
linkage of three genes such as the presence of tendril (t+), dense trichomes (d+), and the
presence of secretory cells (sc+). The loci for the mutant genes have been mapped and are
separated by the following map distances: t and d = 20CM; d and sc = 12CM. The interference
between these genes is 0.4. The first morphotype is located at the lower elevation and is
characterized by the absence of tendril, sparse trichome, and absence of secretory cells. On
the other hand, the second morphotype is located at the higher elevation and is
characterized by the presence of tendril, dense trichome, and presence of secretory cells.
Further genetic analysis showed that the morphotypes were true breeding. The two
morphotypes were intercrossed and the resulting F1 is testcrossed with the first
morphotype. The cross resulted in 1800 progeny. Give the genotypes, phenotypes, and the
expected numbers of phenotypes in…
You are studying a plant with tissue comprising both green and white sectors. You wish to decide whether this phenomenon is due (1) to a chloroplast mutation of the type considered in this chapter or (2) to a dominant nuclear mutation that inhibits chlorophyll production and is present only in certain tissue layers of the plant as a mosaic. Outline the experimental approach that you would use to resolve this problem.
