The primary original source of genetic variation in a population is mutation. Mutations are changes in the DNA sequence that can lead to new genetic variations in populations, providing the raw material for evolution to occur.

What is the role played by the primary sector in developing countries?
The primary sector in developing countries plays a crucial role in providing livelihoods for a large portion of the population, particularly in rural areas. It is also a significant source of export earnings and contributes to food security. However, it faces challenges such as limited access to technology, market volatility, and environmental sustainability issues.
Who serves as a primary connection between the population and the criminal justice system?
Law enforcement officers typically serve as the primary connection between the population and the criminal justice system. They are responsible for investigating crimes, making arrests, and enforcing laws, acting as the initial point of contact for individuals involved in criminal activities.
What is a primary city?
A primary city is typically the largest or most important city within a region or country. It serves as a key hub for economic, cultural, and political activities, and often has a dense population and significant infrastructure compared to other cities in the area.
Which is a primary source that can be used to acquire information about the population of the US in 1963?
The US Census Bureau's decennial census conducted in 1960 would be a primary source for acquiring information about the population of the US in 1963. Additionally, reports from the United States Bureau of the Census or statistical yearbooks published by the US government could also provide valuable demographic data for that period.
What country has the most population of Spanish speakers?
Mexico has the highest population of Spanish speakers, with over 120 million people who speak Spanish as their primary language.
What tends to increase genetic variation in a population?
Genetic variation is the total amount of genetic diversity present within a species or population. The amount of genetic variation in a population will depend on a variety of factors, including the size of the population, the type of reproduction, and environmental influences. The primary way to increase genetic variation in a population is through mutation. Mutations are random changes in the genetic code that can lead to new traits or characteristics. Mutations can be caused by environmental factors, such as exposure to radiation or chemicals, or they can occur spontaneously. Mutations can be beneficial, neutral, or detrimental to the organism, but they do lead to increased genetic variation. Another way to increase genetic variation in a population is through migration. When individuals from different populations mate, they bring with them different alleles from their home population, increasing the genetic diversity of the new population. This is especially important for populations that are geographically isolated, such as island populations. Another factor that can increase genetic variation is sexual selection. This is the process by which individuals select mates based on certain desired traits. This can lead to an increase in the number of different alleles in the population, as individuals with certain traits will be more likely to reproduce. Finally, gene flow is a process that can increase genetic variation in a population. Gene flow is when individuals from one population move to another population and mate with individuals in the new population. This can bring in alleles from the original population, increasing the genetic diversity of the new population. Overall, while mutation, migration, sexual selection, and gene flow are all important factors in increasing genetic variation in a population, it is important to note that genetic variation can also be decreased by inbreeding and genetic drift. Inbreeding is when individuals mate with close relatives, reducing the number of alleles in the population and leading to decreased genetic variation. Genetic drift is when random fluctuations in allele frequencies occur due to a small population size, leading to decreased genetic variation. Therefore, it is important to consider all of these factors when trying to increase genetic variation in a population.
What is the ultimate source of genetic variation and the basis for the diversity of life on earth?
Mutations. These have quite a few different causes. Sexual reproduction is a "more recent source" {beginning 600 million years ago} of genetic variability. The process of sharing genetic information, coupled with the random crossing and mixing of genetic information during the creation of a new organism, leads to another source of genetic variability.
Disadvantages of budding?
budding does not allow any type of genetic variation. The new generation is naturally genetically identical to the primary one(clone) so as with binary fission there is not as much genetic variation in offspring as occurs with sexual reproduction.
What is the primary advantage of sexual reproduction?
Sexual reproduction is more advantageous than asexual reproduction because it allows for genetic diversity. In asexual reproduction there is only one source of genetic material whereas with sexual reproduction there are two sources of genetic material.
What is the primary evolutionary unit is the?
population is the primary evolutionary unit of any living organisms
What is the primary cause of variation in offspring of sexually reproducing organism?
recombination of alleles
Who or what is responsible for it being in danger for white tigers?
White tigers are only a rare genetic variation of the Bengal. None have been seen in the wild for years, but could occur in a normal Bengal litter at any time. Man has been the primary reason for tiger endangerment.
The advantages and disadvantages of primary data?
Advantages and Disadvantages of primary data are: Advantages 1. Data is basic 2. Unbiased information 3. Original data 4. Data from the primary market/ population 5. Data direct from the population. Disadvantages. 1. Large volume of data. 2. Huge volume of population. 3. Time consuming 4. Direct and personal intervention has to be there. 5. Raw data.
Primary vehicle for carrying genetic information from the nucleus to the cytosol?
mRNA
What is the primary cause of changes in the earth's weather?
The primary cause in change to the Earth's weather is variation in solar energy received by the Earth's regions.
What do you understand by the statement DNA is the primary genetic material of the cell?
DNA is the primary genetic material of all cellular organisms and is housed in the nucleus or cytoplasm. DNA controls the cells functions.
What is the primary function of DNA?
DNA is the genetic material of cells. The major function of DNA is to store and transmit genetic (hereditary) information. It does this by providing a code (the genetic code) for the production of proteins by the cell.
