      - Within rare cases, both environmental factors and genetics plays a role within the presentation of phenotypes.
- - - - The power of environmental factors being able to overturn those of genetics is also shown within the research of a Spanish Olympic long jumper reported by New York Time. Within the article, it describes that the Spanish long jumper contains no copies of the 577R allele, an allele of the ACTN3 that suits anaerobic sports, within his genotype. Despite lacking the allele suitable for long jump, the athlete was still able to achieve a high-level of success within the field, thus highlighting the outside effects that influence him, such as training.
    - - Research in mice has found that the glucocorticoid receptor (GR), responsible for stress hormone cortisol in the process of recovering from tense events, are highly dependent upon maternal nurturing within the first few days after birth. As shown in mice, ones that were nurtured, through licking of the mother, had low levels of methylation within the GR gene and lived with low-stress levels throughout their life. However, mice that lacked nurturing were detected with high levels of methylation, thus having low GR expression and high stressed lives.
    - - Sleeping habits are similar to training, as both are actions leading to a change in the body constitution of an individual. In the study done on the connection between sleeping habits and type 2 DM, scientist have found that resistance against insulin increase under sleep restrictions. Within the experiment, Broussard and his colleagues found that the amount of insulin needed to activate 50% of Akt, molecules that signal GLUT4 to transport glucose into the cell, within the cell tripled in amount. As well as this, through the in vivo intravenous glucose tolerance test, it was shown that the total body insulin sensitivity parallels with patients with type 2 DM.
