Genetic psychology, also known as behavioral biology, is a field of study exploring how genes influence personality. (goodtherapy.org)
A very natural place to study gene detecting and metabolizing lactose, it is known that the overall regulation is in the metabolism of the cell, and then specifically in effect of expressing the lac genes in vain is a drop in the growth rate the regulation of genes that code for enzymes and transporter of as much as 5% [1,6]. (lu.se)

It causes inflammation in multiple organs, 1 and 15. (medlineplus.gov)

Family health history reflects the effects of shared genetics and environment among close relatives. (cdc.gov)
It is now known both genetics and environment play a role, and most characteristics are determined by a combination of each. (goodtherapy.org)

Multiple endocrine neoplasia is a group of disorders that affect the body's network of hormone-producing glands called the endocrine system. (medlineplus.gov)

Genetic variance in expression increases at 18 °C relative to 25 °C for most genes that have a change in genetic variance. (nature.com)
Genes with higher network connectivity are under stronger stabilizing selection, suggesting that stabilizing selection on expression plays an important role in promoting network robustness. (nature.com)

It has long been my opinion that many of the complex conditions we face today are the result of our external environment. (betterhealthguy.com)
Experts agree that in the vast majority of cases, Alzheimer's, like other common chronic conditions, probably develops as a result of complex interactions among multiple factors, including age, genetics, environment, lifestyle and coexisting medical conditions. (alz.org)

They have no second allele to mask the effects of a defective gene. (utah.edu)

No other interactions were statistically significant after adjusting for multiple comparisons. (nih.gov)

Rarely, a clear pattern of inherited obesity within a family is caused by a specific variant of a single gene (monogenic obesity). (cdc.gov)
Dominant" means that a single copy of the mutated gene (from one parent) is enough to cause the disorder. (genome.gov)
By contrast, an autosomal dominant disorder requires only a single copy of the mutated gene from one parent to cause the disorder. (genome.gov)

You can't prove a mutation in a gene is responsible for a disease with just one family, Hamosh said. (cnn.com)
If a gene becomes damaged, this damage is called a mutation. (oncolink.org)
Cells that are missing this gene, or have a non-functioning copy because of a mutation, may be "fixed" by adding functioning copies of p53 to the cell. (oncolink.org)
