What is it called when extra copies of part of a chromosome are made?
It is called gene duplication when extra copies of a gene or segment of DNA are created within a chromosome. This process can lead to genetic variation and the emergence of new gene functions.
What also contributes to genetic variation?
The two main sources of genetic variation are gene shuffling and mutations. A mutation is a process wherein the structure of a gene is altered.
All the genes in a given population which can be inherited constitute a?
genetic variation
What is a trait variation that is hidden by the presence of another variation?
A trait variation that is hidden by the presence of another variation is known as epistasis. In genetics, this occurs when the effect of one gene is masked or suppressed by another gene, leading to a phenotype that doesn't fully express all potential traits. For example, in certain plant species, one gene may determine flower color, while another gene may govern the presence or absence of flowers altogether, thus obscuring the color variation. As a result, the observable trait is influenced by the interaction of multiple genes rather than by a single gene alone.
Which characteristic of DNA determines the variation of genetic expression in phenotypes?
The gene sequence of a DNA determines the variation of genetic expression in phenotypes.
What is variation in evolution?
A variation of a gene is called and allele. Different alleles are caused by mutations.
What is it called when extra copies of part of a chromosome are made?
It is called gene duplication when extra copies of a gene or segment of DNA are created within a chromosome. This process can lead to genetic variation and the emergence of new gene functions.
What is inhereited variation with recombination and gene flow?
What is inertied variation with recombination .
What is the movement of genes into and out of a gene pool called?
The movement of genes into and out of a gene pool is called gene flow. Gene flow occurs when individuals migrate between populations and introduce new genetic variation or when individuals leave a population, reducing the amount of genetic diversity.
What is the movement of genes into and out of a a gene pool called?
The movement of genes into and out of a gene pool is called gene flow. Gene flow occurs when individuals migrate between populations, bringing new genetic variation into a population, or when genetic material is transferred through reproduction between populations.
What is a different between allele and gene?
an allele is a gene that is the cause of hereditary variation
Which example of genetic variation is a variant of a gene?
One example of genetic variation that is a variant of a gene is a single nucleotide polymorphism (SNP), which is a change in a single DNA building block within a gene.
The collection of all the genes in a population is called?
The collection of all the genes in a population is called the gene pool. This gene pool contains all of the genetic variation within a population, which can be passed on to future generations through reproduction.
What is the term for the fact that individuals in a population are slightly different from each other?
The term for the slight differences among individuals in a population is "genetic variation." This variation is crucial for evolution and natural selection, as it provides the raw material for adaptation to changing environments. Genetic variation can arise from mutations, gene flow, and sexual reproduction, contributing to the diversity within a species.
Where is genetic variation stored in a population?
In the gene pool
Where is genetic variation stored in population?
In the gene pool
What is RNA gene drift?
gene drift is when a population experiences a decrease in variation and population size.
