There is only one measure of "evolutionary success": having more offspring. A "useful" trait gets conserved and propagated by the simple virtue of there being more next-generation individuals carrying it and particular genetic feature "encoding" it. That's all there is to it.
One can view this as genes "wishing" to create phenotypic features that would propagate them (as in "Selfish Gene"), or as competition between individuals, or groups, or populations. But those are all metaphors making it easier to understand the same underlying phenomenon: random change and environmental pressure which makes the carrier more or less successful at reproduction.
You will sometimes hear the term "evolutionary successful species" applied to one that spread out of its original niche, or "evolutionary successful adaptation" for one that spread quickly through population (like us or our lactase persistence mutation), but, again, that's the same thing.
Answer:
In biology, cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells
Answer:
The correct answer is inheritance.
Explanation:
Genetic characteristics are transferred from one generation to another.The mechanism of transfer of genetically determined characteristics from generation to generation is called inheritance.
Genetic characteristics are stored within the sex chromosome of both male(XY) and female(XX).During fertilization when the sperm cells fuses with ovum at that time some characteristics of both male and female gets incorporated into the diploid zygote which give rise to the new organism containing inherited genetic characteristics.
Answer:
it's in the explanation
Explanation:
meiosis produces haploid gametes (ova or sperm) that contain one set of 23 chromosomes. when two gametes (an egg and a sperm) fuse, the resulting zygote is once again diploid, with the mother and father each contributing 23 chromosomes
False. Energy is never destroyed, it can only be transformed. Energy is never lost as well.
