inherited variation
Some organisms have evolved to reproduce asexually due to the fact they may not be in a stable enough environment for them to reproduce sexually. Often times the population of an organism will be smaller if they reproduce asexually and they will have a much small gene pool.
In Darwin's theory of evolution, over-reproduction means that organisms tend to produce more offspring than can survive in their environment due to limited resources and competition. This leads to a struggle for existence, where only the fittest individuals with advantageous traits are able to survive and reproduce.
The fact that all organisms have the same basic metabolism was discovered through research and comparison of biochemical pathways in different organisms. Scientists have identified commonalities in fundamental biological processes, such as glycolysis, Krebs cycle, and ATP production, which are universally present in all living organisms. This knowledge has advanced our understanding of the unity of life and evolution.
There are no ' doctrines ' of evolution. Evolution, the change in allele frequency over time in a population of organisms, is fact. The theory of evolution by natural selection explains, to a great degree, this fact. The theory is supported by mountains of evidence, from fossils to molecular genetics. Science does not have doctrines.
More information is needed. The percent of offspring that will display the recessive trait from parents with Hh and HH will be different than the percent of offspring that will display the recessive trait from parents with hh and Hh.
The females do the rearing of the offspring. In fact, some male animals are known for eating their own offspring, like Lions. Males are usually highly aggressive to their offspring.
They must be able to reproduce, and their offspring must be fertile as well. So technically, because ligers are in fact fertile, tigers and lions are one species, regardless of the fact we classify them as two.
Male seahorses carry the offspring, not the females.
Identical twins, due to the fact that the one fertilized egg splits, have identical DNA. Fraternal twins, since they are from separate eggs, have different DNA.
They are all alive.

Yes, they were called hobnails. An interesting fact about them is that the pattern of the nails in the Roman military boot was identical to the pattern of support used in present day training shoes.Yes, they were called hobnails.

As a matter of fact,they are.
Atheism and Evolution are two different things that are often miscombined. Atheism is a belief or philosophy that there are no Deities. Evolution is a biological process whereby the structure and genetic code of organisms change over many generations, as particularly unsuccessful organisms die without offspring and particularly successful organisms are likely to have more offspring. The characteristics of the successful organism thus become the norm.There is no particular reason to link them, other than the fact that atheists are less likely to reject evolution on the basis of their philosophy.
Humans are generally not considered typical organisms. In fact, humans are often considered unique organisms simply due to their complexity.
Clones are organisms that are genetically identical to another organism from which they were derived. This can occur naturally, as in the case of identical twins, or artificially through processes like somatic cell nuclear transfer, as seen in the famous case of Dolly the sheep. Cloning can be used for various purposes, including research, agriculture, and conservation. However, ethical considerations often arise regarding the implications and consequences of cloning.
Due to the fact that we can not clone people yet, we don't know yet, but from what we know, yes.
