What is an allele and how does it contribute to genetic variation in organisms?
An allele is a variant form of a gene that determines a specific trait. Alleles contribute to genetic variation in organisms by creating different combinations of traits through genetic recombination during reproduction. This variation allows for diversity within a population, which can lead to adaptations and evolution over time.
How do pair of chromosomes contribute to genetic inheritance and variation in organisms?
During reproduction, a pair of chromosomes from each parent combine to create a unique genetic makeup for the offspring. This process leads to genetic inheritance and variation in organisms, as the combination of genes on the chromosomes determines the traits and characteristics of the offspring.
How does standing genetic variation contribute to the overall genetic diversity within a population?
Standing genetic variation refers to the existing genetic differences within a population. This variation contributes to genetic diversity by providing a pool of different genetic traits that can be passed on to future generations. This diversity helps populations adapt to changing environments and increases their chances of survival.
How does the process of mutation contribute to genetic variation, and how is the randomness of mutations important in evolution?
Mutations are changes in the DNA sequence that can lead to genetic variation. These variations can result in new traits or characteristics in organisms. The randomness of mutations is important in evolution because it introduces new genetic material into a population, which can lead to adaptations that help organisms survive and reproduce in changing environments.
What is a homologous pair and how does it contribute to genetic variation in organisms?
A homologous pair is a pair of chromosomes that have the same genes in the same order. During meiosis, homologous pairs exchange genetic material through a process called crossing over. This genetic recombination creates new combinations of genes, leading to genetic variation in offspring.

What is a source of genetic variation in organisms?
Human recombination is a significant source of genetic variation.

Which is a source of genetic variation in sexually-reproducting organisms?
Basic source of variation in all organisms is mutation .
What is genetic variation in natural selection?
Natural selection ' selects ' from among variations. Some organisms are better suited to their immediate environment and survive and out reproduce other organisms. All these organisms are genetically variant. That is the simple connection between natural selection and genetic variation. ( that variation coming about by mutation and recombination )
Which events contribute to genetic variation?
fertilization

Is genetic variation found only in wild organisms in nature?
No.
How does genetic diversity contribute to the survival of a species?
Genetic diversity is important for the survival of a species because it increases the chances of individuals having traits that can help them adapt to changing environments or resist diseases. This variation allows a species to better withstand threats and increases its overall resilience.
