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.

Why does meiosis result in more genetic variation than mitosis?
It would be wrong to consider mitosis insignificant as it helps in cell repair and replacement in our daily life and it would be impossible to survive without it and asexual reproduction as well but if it weren't for meiosis, none of us would have been born :) Meiosis is responsible for the division for our gamete cells which leads to the formation a zygote. from there on mitosis takes over.

What are sexual advantages?
Where genetic information is shared by gametes from two parents it produces variety in the offspring. This variety can then allow a species to evolve to exploit different environments.
What are Advantages of sexual?
Where genetic information is shared by gametes from two parents it produces variety in the offspring. This variety can then allow a species to evolve to exploit different environments.
What results in the most diverse offspring?
Sexual reproduction leads to variety in offspring.
What ares advantages of sexual reproduction?

Which type of reproduction sexual or asexual results in offspring with greater gentic variation?
Sexual reproduction results in the greatest variety of inherited traits in the resulting offspring. Asexual reproduction produces very little variation in traits - the offspring are virtually identical to the parent organism.

Why might crossing over be beneficial?
Linked genes do not assort independently since they are found on the same chromosome. Crossing over is a random process that occurs during prophase I ofmeiosis. It occurs in the tetrads when pieces of two homologous chromosomes switch places with each other. The new chromosomal set up is different from the original homologs found in the cell before prophase I began. A test cross must be conducted in order to demonstrate the process of crossing over. A test cross is the mating of a heterozygous individual for both characteristics with a homozygous recessive one for both characteristics. Crossing over produces variety within the species. The more variety the more chances the species has to adapt to a changing environment. Meiosis produces a variety of gametes designed to foster this kind of diversity.
What would most likely decrease the genetic variation in the human population?
A widespread disaster would reduce the variety within the human genetic pool by eliminating all but certain segments of the population. A global plague could potentially have the greatest effect, as plagues (see: black plague, Spanish influenza) often will often decimate all of a local population save for those with genetic immunity--thus standardizing that mutation in future populations. Global catastrophe could also inhibit travel, and would limit human reproduction to their immediate region, limiting the genetic range of potential offspring.
What can mutations be a source of?
Mutations create changes in the genetic code. There are different types of mutations and vary in degree of harm or even benefit to the organism. If the mutation happens to be beneficial to the organism, then it can be passed down to its offspring and thus this leads to genetic variation in the population.
Variety in species exists exist because?
Variety in species exists due to genetic variation that arises from random mutations and recombination of genes during reproduction. This variation allows species to adapt to different environments, enabling them to survive and reproduce in diverse conditions. It also promotes biodiversity, which is essential for ecosystem stability and resilience.
What is the advantage of meiosis over binary fission?
the benefit of meiosis is that there is genetic recombination hence, helps in variation of characters .that is the reason why children are SIMILAR to their parents but DO NOT look like them completely.
