A Quote by Gregor Mendel
My experiments with single traits all lead to the same result: that from the seeds of hybrids, plants are obtained half of which in turn carry the hybrid trait (Aa), the other half, however, receive the parental traits A and a in equal amounts. Thus, on the average, among four plants two have the hybrid trait Aa, one the parental trait A, and the other the parental trait a. Therefore, 2Aa+ A +a or A + 2Aa + a is the empirical simple series for two differing traits.

When two plants, constantly different in one or several traits, are crossed, the traits they have in common are transmitted unchanged to the hybrids and their progeny, as numerous experiments have proven; a pair of differing traits, on the other hand, are united in the hybrid to form a new trait, which usually is subject to changes in the hybrids' progeny.
If A denotes one of the two constant traits, for example, the dominating one, a the recessive, and the Aa the hybrid form in which both are united, then the expression: gives the series for the progeny of plants hybrid in a pair of differing traits.
Trait X is fitter than trait Y in a population of organisms if those organisms have other biological traits T and live in an environment that has properties E. The theory of natural selection is filled with statements of this form.
The sociopath wants the person to be easily enough fooled to stick with him. This can be accomplished by looking for someone who is very, very loyal. Most of us consider loyalty to be a very positive trait - and it is a positive trait. But it also blinds people to some of the traits of the person they're loyal to.
Those traits that pass into hybrid association entirely or almost entirely unchanged, thus themselves representing the traits of the hybrid, are termed dominating and those that become latent in the association, recessive.
Darwin and his successors have railed against the fallacy of confusing the current utility of a trait with the reason the trait evolved. For example, Darwin argued that skull sutures in mammals did not evolve because they facilitate live birth; the sutures were in place well before live birth evolved. Checking the chronological order in which different traits evolved in a lineage is one way to test an adaptive hypothesis; the fact of common ancestry is what makes that checking possible.
As trait after trait swings into focus and fulfillment, can we write any other name under Isaiah's amazing portrait of the sublime Sufferer in Chapter 53 than Jesus of Nazareth?
Why is it that, among men, physical courage is a trait so plenteous yet moral courage is a trait so rare?
Whereas recessive traits require two bad copies of a gene to become noticeable, a dominant trait expresses itself no matter what the other copy does. A benign example of dominance: If you inherit one gene for sticky wet earwax and one gene for dry earwax, the sticky earwax gene wins out every time.
I try not to confuse roles and traits in my own life. Being the Perl god is a role. Being a stubborn cuss is a trait.
As conscious adult women, we need to instill a different value system. Actually, it is an innate value system. We need to tell the world that being compassionate about other people does not make you weak, and it is not intrinsically a female trait. It is a trait of the evolved human being, and it is a trait that we need to hold up as something of great worth. As women, we need to promote that, emphasize that, and nurture that. This is part of what we are doing with Global Girl Media.
It's often meaningless to talk about a genetic trait without also discussing the environment in which that trait appears. Sometimes, genes don't work at all until the environment awakens them.
In this generation, along with the dominating traits, the recessive ones also reappear, their individuality fully revealed, and they do so in the decisively expressed average proportion of 3:1, so that among each four plants of this generation three receive the dominating and one the recessive characteristic.
Scientists have one thing in common with children: curiosity. To be a good scientist you must have kept this trait of childhood, and perhaps it is not easy to retain just one trait. A scientist has to be curious like a child; perhaps one can understand that there are other childish features he hasn't grown out of.
Gentleness is an active trait, describing the manner in which we should treat others. Meekness is a passive trait, describing the proper Christian response when others mistreat us.
A most highly multiplying trait in point of far-reaching influences is that of ability to discover and use strong men. This trait stands out impressively in Rothschild's 'Lincoln, Master of Men'.
