When our parents pass away we inherit their possessing. Don't we? The same is said about our genes. We inherit 50% of our genes from mother and 50% from father. Most of our physical features are determined by our genes that we inherited from our parents. The same can be said about our psychological feature. For example, personality is in somewhat is inherited feature from our parents, and in somewhat is socially learned - determined by environmental factors such as education and family influence. Hope this helps

What is heretibility?
I believe you are referring to heritability, which is the concept used in debates about nature versus nurture.For the source and more detailed information concerning this subject, click on the related links section (Answers.com) indicated below this answer box.
What percentage of intelligence is inherited?
Intelligence is estimated to have a heritability of around 50-80%, meaning that genetics play a significant role in determining intelligence. However, environmental factors, such as education and upbringing, also play a crucial role in shaping an individual's intelligence.
What theories suggest that important components of personality are inherited?
Theories such as the biological theory of personality suggest that important components of personality, such as temperament and traits, are influenced by genetic factors passed down from parents. Research on heritability estimates also supports the idea that genetic factors play a significant role in shaping aspects of personality. Twin studies and family studies have provided evidence that genetics contribute to the development of personality characteristics.
Why are twin studies important?
Twin studies are important because, as in any scientific experiment, it is important to reduce the number of variables and have a good control group. Twins are genetically identical so it can be assumed any differences in their mental makeup are due to "nurture" rather than "nature". Also, in a drug trial, if one is given a drug and the other given a placebo, any effects shown in the twin that took the drug and not seen in the twin that took the placebo can be assumed to be a result of the drug, not any underlying genetic reaction to the drug.
What genetic characteristics come from the bull?
Half the genes a calf gets is from his sire, and the other half from his dam. Some genes will be more dominant than others, depending on which of his parents has the dominant gene, and some, like carcass characteristics from his sire, are more heritable than others. Often a bull that has better genetics than the rest of the cowherd will produce calves that have slightly better genetics than their dams. Some of the more heritable traits that a bull's offspring can receive from him, if he's better quality than the cowherd, are: Lean/bone ratio (60% heritability) Lean percentage (55% heritability) Mature cow weight (50% heritability) Carcass grade (45% heritability) Thickness of outside carcass fat (45% heritability) Dressing percentage (40% heritability) Marbling (40% heritability) Ribeye area (40% heritability) Yearling weight (feedlot)(40% heritability) Yearling weight (pasture (35% heritability) Efficiency of gain (35% heritability) Birth weight (30% heritability) Post-weaning gain (30% heritability) Tenderness (meat quality) (30% heritability) Carcass weight (25% heritability) Weaning weight (25% heritability) Calf survival (10% heritability) Calving interval (10% heritability) Calving ease (10% heritability) The definition of heritability is: "The proportion of the differences among cattle, measured or observed, that is transmitted to the offspring. Heritability varies from 0 to 1. The higher the heritability of a trait, the more accurately does the individual performance predict breeding value and the more rapid should be the response due to selection for that trait."
Is Heritability of all traits the same?
No, heritability varies for different traits. While some traits have a high heritability (such as height or intelligence), others have a lower heritability (such as personal preferences or habits). The heritability of a trait depends on how much of the variation in that trait can be attributed to genetic differences among individuals in a specific population.
Given a uniform environment the extent to which trait variation can be attributed to differing genes is called?
Heritability
What is the maximum value for heritability?
Heritablility values range from 0-1 so the maximum value of heritability would be 1.
The current estimate of heritability of intelligence is?
90
What are the strengths and weaknesses of some of the methods used to determine heritability in humans?
Heritability is the amount of variance in observed demeanors among people that can be explicated by genetics.
What would contribute to an overestimation of heritability?
One of manyÊthings that could contribute to incorrect or overestimation of heritability would be the infuence of environment factors including geographical location.
Difference between broad sense heritability and narrow sense heritability?
Broad sense heritability A.K.A (H) is the degree in which phenotypic variation is due to genetic factors Narrow sense heritability A.K.A (h) is the degree in which phenotypic variation is due to additive genetic factors. in maths terms... H = Vg/Vt h = Va/Vt Vg= genetic varaition Vt = total variation Va = additive variation
What is the estimated influence of genes on a trait called?
heritability
Why is high heritability more desirable than low heritability?
High heritability indicates that genetic factors play a significant role in determining a trait, making it more predictable and potentially easier to manipulate in breeding programs or genetic studies. In contrast, low heritability suggests that environmental factors have a larger influence, leading to less consistency across generations and making it harder to select for or study specific traits.
How is heritability related to evolution?
Heritability is the proportion of variation in a trait within a population that can be attributed to genetic differences. This is important in evolution because traits with high heritability can be passed down from one generation to the next, allowing for natural selection to act on these traits over time, leading to evolutionary changes in a population.
The likelihood of a trait being passed of from parent to offspring?
heritability.
