∙ 14y agowhen you observe members of your own species, you can see a large variation in traits. Because people have 46 chromosomes and about 50,000 genes, there is an enormous number of possible combinations.

How do organisms achieve variation?
The differences shown by the individuals of one kind of organisms are called variations. Variations are due to hereditary and non-hereditary characteristics. Characteristics, which are passed from parents to off spring, are called hereditary characteristics. In general the term variation means the difference in characteristics of organisms belonging to the same species in a natural population. Two types of variation, i.e. continuous and discontinuous, occur in any large population. In continuous variation, there are small differences among individuals of the same species and many intermediate forms are seen. So there is a complete gradation of many characteristics of organisms from one extreme to the other in a population. E.g. height in human being. Characteristics showing continuous variation are produced due to combined effects of many genes and environmental factors.
How are organisms that reproduce asexually linked to their parents?
Organisms that reproduce asexually make exact copies of themselves. So, they are "clones" of their parents. Of course, some differences may appear because of mutations (changes in the DNA due to errors during replication), though.
Is this true or faulse an offspring produced through sexual reproduction has the exact same genetic information as its parents?
true
What are same organisms?
They're the same.
What group of organisms can mate and produce fertile offspring?
They are members of the same species.
Slight differences among objects or organisms that are all of the same basic type such as difference among individual golden retriever dogs?
variations variations
What is the phenotype produced between the two homozygous parents?
The same phenotype as both of the parents.
What produces offspring's that are similar to parents?
all organisms can divide to produce same offspring that are similar to the parents

What is the chance of two guns producing the same striations?
So close to zero as being unmeasurable. The variations in markings come from random variations in wear of the rifling cutter, odd chips of steel produced by the rifling process, etc. Even two guns made in succession on the same production line will show differences in produced striations.
What is the main points of Darwin's theory of evolution?
That all organisms are variations. That there are many more organisms born than can be supported by the available resources. That their is a struggle for existence and some organisms will be better adapted to survive and out reproduce their fellow organisms. That these organisms that do this will leave descendents that have these same characteristics which will change the morphology and behavior in these population of these organisms over time.
How does the pairing of gamets produce genotypic variations?
Simply put you get one copy of each chromosome from your dad and one copy from your mom. Since your parents aren't the same and don't have the same alleles, you will get a pretty even mix of your parents.

Is that true the environment favors certain variations in organisms over others?
I believe what you're referring to is natural selection. In short, yes it does. Certain organisms have characteristics that allow them to survive more efficiently in a certain environment than other organisms of the same species. As a result, these organisms survive to reproduce, thus passing on these efficient variations to their offspring, and so the cycle continues. The organism without these variations is less likely to survive, meaning it will be unable to reproduce and pass on it's characteristics. Eventually, this will cycle out the characteristics or variations that aren't adequate for surviving in said environment, and only the well-equipped will survive. This process is more commonly known as "survival of the fittest."
Which organism would share the most characteristics?
organisms in the same order (APEX)
What will happen if all organisms reproduce asexually?
Everyone will be exactly the same as their parent. Organisms that reproduce asexually, cells for example, create a genetic copy of themselves. Where as organisms that reproduce sexually, humans for example, get their genes from both parents and end up being a unique combination of their parents.
