Genetic variation occurs through random gene mutation all the time and espescially during meiosis where different allele combinations occur through the formations of chiasma in prophase and as part of random separation in anaphase
this will create a unique arrangement of genetic variations in the genotype which will be presented, naturally, through the phenotype
What else can I help you with?
What causes variation within species?
because the variation causes the variation becasue of the variation of the species. genetic mutation and adaption of some members to physical condition better than others (survival and reproduction of those best able to adapt to the environment. ) It can also be affected by the contact the species has doesn't have with other populations of the species.
Which groups is the smallest level of classification?
The smallest level of classification is a species. It is the basic unit of classification and represents a group of organisms that are capable of interbreeding and producing fertile offspring.
What is the correct way to write a scientific names?
Scientific names should be written in italics with the genus capitalized and the species in lowercase. The genus name is always written before the species name. For example, the scientific name for the housecat is Felis catus.
What is an animal species?
In general, a species is a group of similar organisms that can interbreed and produce fertile offspring. More specifically, species can be defined as a group that has similar morphology, DNA, geographic distribution, and occupies the same ecological niche.The official definition for the word species is "a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. The species is the principal natural taxonomic unit, ranking below a genus and denoted by a Latin binomial, e.g., Homo sapiens."
The eight levels of classification from general to specific is?
The eight levels of classification from general to specific are domain, kingdom, phylum, class, order, family, genus, and species. These levels are used in the Linnaean classification system to categorize and organize living organisms based on their shared characteristics.
Variation exists within the genes of every population or species as the result of what?
Variation exists within the genes of every population or species as the result of natural selection. The other reason is due to neutrality of mutations.
What is phenotypic variation?
Phenotype variation is slight variations in a phenotype that are caused by the expression of an organism's genes or the influence of environmental factors. A species can have several different phenotypes within it.
What allows variation among a species that reproduces sexually?
The combination of genes
Does variation within the same species exist?
Of course, variation exists within individuals of the same species. This is because there are a small minority of genes which have multiple alleles in most species. In cases where a subset of the population is isolated from the rest of the population, a subspecies may develop which has particular unique characteristics but can still interbreed with the rest of the species.
What causes variation within species?
because the variation causes the variation becasue of the variation of the species. genetic mutation and adaption of some members to physical condition better than others (survival and reproduction of those best able to adapt to the environment. ) It can also be affected by the contact the species has doesn't have with other populations of the species.
Individuals of species that reproduce sexually tend to lack variation True False?
False. Individuals of species that reproduce sexually tend to have more variation because each offspring inherits a unique combination of genes from both parents, leading to genetic diversity within the population.
Why fertilized human is important?
Fertilization is important so species can have genetic variation. It is also important so the species can pass on their genes.
What are the individual differences in genes among members of a species make up the total?
Well, isn't that a lovely question! Just like how every tree in a forest is unique, each member of a species carries their own set of genes that make them special. These differences create a beautiful tapestry of diversity within the species, much like how each brushstroke adds depth and richness to a painting. So, embrace your uniqueness and know that you are an important part of the larger picture of life.
How does natural selection produce genetic variation within a species?
It's mainly mutations in the DNA and recombination of chromosomes that produce the genetic variation. Natural selection then favors those changes that give rise to greater reproductive success.
How come there is variation of species?
Some reasons:Sexual reproduction exchanges genes every generationmutationstranscription errorsretroviruses can move genes across species linesbacteria increase their diversity by exchanging plasmids (sometimes across species lines)etc.
What characteristic within populations cause natural selection to occur?
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
What is the significance of sexual mode of reproduction?
Sexual reproduction allows for greater variation and adaptability within a species because changes in DNA can accumulate through both mutation within the DNA sequence as well as by recombination with different versions of the genes.
