Tables

Table: environment

The environmental component of a phenotype description.

environment_cvterm_id serial PRIMARY KEY

environment

environment_id integer UNIQUE#1 NOT NULL

cvterm

Table: feature_genotype

feature_genotype Structure
F-Key Name Type Description
feature_genotype_id serial PRIMARY KEY

feature

feature_id integer UNIQUE#1 NOT NULL

genotype

genotype_id integer UNIQUE#1 NOT NULL

feature

chromosome_id integer UNIQUE#1

A feature of SO type "chromosome".
rank integer UNIQUE#1 NOT NULL

rank can be used for n-ploid organisms or to preserve order.
cgroup integer UNIQUE#1 NOT NULL

Spatially distinguishable group. group can be used for distinguishing the chromosomal groups, for example (RNAi products and so on can be treated as different groups, as they do not fall on a particular chromosome).

cvterm

cvterm_id integer UNIQUE#1 NOT NULL


Table: genotype

This page or section needs to be edited. Please help by editing this page to add your revisions or additions.

OPEN QUESTION: for multicopy transgenes, should we include a 'n_copies' column as well?

Genetic context. A genotype is defined by a collection of features, mutations, balancers, deficiencies, haplotype blocks, or engineered constructs.

genotype Structure
F-Key Name Type Description
genotype_id serial PRIMARY KEY
name text

Optional alternative name for a genotype, for display purposes.
uniquename text UNIQUE NOT NULL

The unique name for a genotype; typically derived from the features making up the genotype.
description character varying(255)

Table: phendesc

A summary of a _set_ of phenotypic statements for any one gcontext made in any one publication.

Table: phenotype_comparison

Comparison of phenotypes e.g., genotype1/environment1/phenotype1 "non-suppressible" with respect to genotype2/environment2/phenotype2.

Table: phenstatement

Phenotypes are things like "larval lethal". Phenstatements are things like "dpp-1 is recessive larval lethal". So essentially phenstatement is a linking table expressing the relationship between genotype, environment, and phenotype.
