Quotes About Heritable

Hereditary honors are a noble and a splendid treasure to descendants.

One reason for the low correlations between individuals' circumstances and their satisfaction with life is that both experienced happiness and life satisfaction are largely determined by the genetics of temperament. A disposition for well-being is as heritable as height or intelligence, as demonstrated by studies of twins separated at birth.

For me, the level at which natural selection causes the phenomenon of adaptation is the level of the replicator - the gene.

One gene may be regarded as a unit that survives through a large number of successive individual bodies.

A germ-line replicator (which may be active or passive) is a replicator that is potentially the ancestor of an indefinitely long line of descendant replicators. A gene in a gamete is a germ-line replicator. So is a gene in one of the germ-line cells of a body, a direct mitotic ancestor of a gamete.

As I said, the active/passive distinction cuts across the germ-line/dead-end distinction. All four combinations are conceivable.

A gene is defined as any portion of chromosomal material that potentially lasts for enough generations to serve as a unit of natural selection.

In principle, we may consider any portion of chromosome as a potential candidate for the title of replicator.

The contrary notion—that individual differences could not easily be diminished by government intervention—collided head-on with the enthusiasm for egalitarianism, which itself collided head-on with a half-century of IQ data indicating that differences in intelligence are intractable and significantly heritable

Hereditary honors are a noble and a splendid treasure to descendants.

The result will be gradual transmutation of heritable forms, and adaptation to circumstances, by a process of selective culling. Eventually he gave the crank a name: natural selection. Twenty years passed after the E notebook entry. The world heard nothing about natural selection.

This broader notion of fitness is called "inclusive fitness" to distinguish it from the notion of "personal fitness," which we have discussed until now.50 The two notions are not at odds. Inclusive fitness simply recognizes a broader spectrum of strategies by which genes muscle into the next generation.

race was defined as an inheritable trait

I don't like the term 'dynasty.'

the broad definition of "epigenetic" used by the U.S. National Institutes of Health as "changes in the regulation of gene activity and expression that are not dependent on gene sequence," including "both heritable changes in gene activity and expression (in the progeny of cells or individuals) and also stable, long-term alterations in the transcriptional potential of a cell that are not necessarily heritable.

I'm pretty sure there is some genetic component towards intelligence.

Some behaviour is more heritable than others; you may start off with some genes loaded for depression but they don't just switch on without some environmental input. No one knows if you become 'you' because of nature or nurture: it's a combination of what you're born with and how you live your life. In

In fact, happiness is one of the most highly heritable aspects of personality. Twin studies generally show that from 50 percent to 80 percent of all the variance among people in their average levels of happiness can be explained by differences in their genes rather than in their life experiences. 28 (Particular episodes of joy or depression, however, must usually be understood by looking at how life events interact with a person's emotional predisposition.)

All five of the major personality dimensions are heritable, with perhaps 40 to 50 percent of the variation in a typical population tied to differences in their genes.

But the ability to lead a nation is not a heritable trait like hair color or skin tone. It is a rare skill, indeed, and manifests itself only in persons whose unique combination of temperament, training, and experience have made them capable of seeing past the benefits that they can derive from their country, to the benefits that they can bestow upon that country.

The general rule is that anything that is passed on in reproduction does not undergo senescence.

What life half gives a man, posterity gives entirely.

As a result, over the course of history, human populations repeatedly exposed to a particular pathogen have come to consist of a higher proportion of individuals with those genes for resistance—just because unfortunate individuals without the genes were less likely to survive to pass their genes on to babies.

Studies of twins have shown that psychopathy may be a trait more heritable than environmental, yet good children can thrive despite bad parents, and vice versa.
