Autosomal genetic disorders which exhibit Mendelian inheritance can be inherited either in an autosomal dominant or recessive fashion. [7] These disorders manifest in and are passed on by either sex with equal frequency. [7] [8] Autosomal dominant disorders are often present in both parent and child, as the child needs to inherit only one copy ...
Autosomal dominant and autosomal recessive inheritance, the two most common Mendelian inheritance patterns. An autosome is any chromosome other than a sex chromosome.. In genetics, dominance is the phenomenon of one variant of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome.
While this definition is more broad, sex-limited genes are certainly included in this category. One of the key principles of sex-biased gene expression that Parsch and Ellegren stressed in their paper in February 2013 [13] is that of rapid evolution. They assert that a gene's sex bias can vary among different types of tissues throughout the ...
The start of behaviour genetics as a well-identified field was marked by the publication in 1960 of the book Behavior Genetics by John L. Fuller and William Robert (Bob) Thompson. [ 1 ] [ 10 ] It is widely accepted now that many if not most behaviours in animals and humans are under significant genetic influence, although the extent of genetic ...
Each autosomal gene is therefore represented by two copies, or alleles, with one copy inherited from each parent at fertilization. The expressed allele is dependent upon its parental origin. For example, the gene encoding insulin-like growth factor 2 (IGF2/Igf2) is only expressed from the allele inherited from the male. Although imprinting ...
Oculocutaneous albinism type I or type 1A [1] is form of the autosomal recessive condition oculocutaneous albinism that is caused by a dysfunction in the gene for tyrosinase (symbol TYR or OCA1). The location of OCA1 may be written as "11q1.4–q2.1", meaning it is on chromosome 11 , long arm, somewhere in the range of band 1, sub-band 4, and ...

For humans, the Big Five personality traits, also known as the five-factor model (FFM) or the OCEAN model, is the prevailing model for personality traits. When factor analysis (a statistical technique) is applied to personality survey data, some words or questionnaire items used to describe aspects of personality are often applied to the same person.
