  2. Pedigree chart - Wikipedia

    en.wikipedia.org/wiki/Pedigree_chart

    Analysis of the pedigree using the principles of Mendelian inheritance can determine whether a trait has a dominant or recessive pattern of inheritance. Pedigrees are often constructed after a family member afflicted with a genetic disorder has been identified. This individual, known as the proband, is indicated on the pedigree by an arrow. [5]

  3. Dog health - Wikipedia

    en.wikipedia.org/wiki/Dog_health

    As with humans, obesity can cause numerous health problems in dogs (although dogs are much less susceptible to the common cardiac and arterial consequences of obesity than humans are). According to a study published in the Journal of Veterinary Internal Medicine , the prevalence of obesity in dogs is between 22 and 40 percent.

  4. Genetics of obesity - Wikipedia

    en.wikipedia.org/wiki/Genetics_of_obesity

    Like many other medical conditions, obesity is the result of an interplay between environmental and genetic factors. [2] [3] Studies have identified variants in several genes that may contribute to weight gain and body fat distribution, although only in a few cases are genes the primary cause of obesity. [4] [5]

  5. Nutritional genomics - Wikipedia

    en.wikipedia.org/wiki/Nutritional_genomics

    Obesity is one of the most widely studied topics in nutritional genomics. Due to genetic variations among individuals, each person could respond to diet differently. By exploring the interaction between dietary pattern and genetic factors, the field aims to suggest dietary changes that could prevent or reduce obesity.

  6. Heritability - Wikipedia

    en.wikipedia.org/wiki/Heritability

    Heritability is an important concept in quantitative genetics, particularly in selective breeding and behavior genetics (for instance, twin studies). It is the source of much confusion due to the fact that its technical definition is different from its commonly-understood folk definition.

  7. Genetic correlation - Wikipedia

    en.wikipedia.org/wiki/Genetic_correlation

    A genetic correlation of 0 implies that the genetic effects on one trait are independent of the other, while a correlation of 1 implies that all of the genetic influences on the two traits are identical. The bivariate genetic correlation can be generalized to inferring genetic latent variable factors across > 2 traits using factor analysis ...

  9. Thrifty gene hypothesis - Wikipedia

    en.wikipedia.org/wiki/Thrifty_gene_hypothesis

    Prentice et al. [17] predicted that the emerging molecular genetics field would ultimately provide a way to test between the adaptive 'thrifty gene' idea and the non-adaptive 'drifty gene' idea because it would be possible to find signatures of positive selection in the human genome, at genes that are linked to both obesity and type 2 diabetes ...
