offspring recieve different combinations of genes from each parent.
Yes, they can.
An allotransplantation is a transplantation of organs or tissues between genetically different individuals of the same species.
they can inter breed and produce fertile offspring.
The union of male and female reproductive cells from different individuals of the same species.
Polymorphism occours when there are different kinds of individuals although they're they are of the same species; for example, in an ant community, there are:* workers * soldiers * drones * queen which are physically different, although they belong to the same population of the same species. Also differences between masculine and feminine are example of polymorphism.
I think it's environmental and genetic.
The number of chromosomes can vary widely between species. However, in general, individuals of the same species have the same number of chromosomes.
No two organisms have identical DNA, It depends on the molecular marker and species, DNA fingerprinting is a technique that is used to identify patterns that occur in DNA. One of the method consist using Restriction enzymes. Restriction enzymes always cut at the same base sequence. Because no two individuals have identical DNA, no two individuals will have the same length fragments. Different species of organisms have different proportions of bases.
An evolutionary mechanism that keeps individuals of different species from interbreeding, even if they live in the same environment.
An allotransplant is another word for an allograft, a surgical transplant of tissue between genetically different individuals of the same species.
no they can be but aren't always from the same species
A population.
