Tremendous natural variation of growth and development exists within species.
Our observation suggested that the measured gene expression differences between the 509 B. napus inbreds were more than adequate for the correlation with phenotypic variation of seedling development.

Up to now, however, little is known about the genetic mechanisms as well as the natural variation of seedling development in B. napus.
However, variation among cows in circulating E1SO4 levels during late pregnancy may be caused by variation of placental development, oestrogen production and conjugation [ 31] and the specific responses of maternal and foetal units [ 29].
Also, we did not study the improvement of delays over time, and it is not fully clear which of those represent just a variation of individual development and which some form of a permanent pathology.
However, because of the cross-sectional nature of these studies, it is unclear whether the cam deformity formation is a secondary reaction to physical stress or whether it represents a variation of physeal development.
DSM-4 used the term Gender Identity Disorder (GID) but was replaced due to the pathologizing nature of the concept that Transgender is a "disorder", not a natural part of the variation of human development, although only a small percentage of the population has this variation.
Together they explained 37%% of the variation for development rate (Fig. 7; Table 10).
Various studies suggest that common DNA sequence variants in genes, especially single nucleotide polymorphisms (SNPs) are responsible for many of these examples of variation in development of diseases, responses to pathogens, chemicals and drugs (Erichsen and Chanock, 2004; Bondy, 2007; Giacomini, Brett et al. 2007; Owen and McCarthy, 2007; Rabik and Dolan, 2007).
