Crossing over of sister chromatids in prophase 1 of meiosis, independent assortment along the metaphase plate in metaphase 1 of meiosis.
Not sure what a third one is.
-------------------------------------------------------------------
There are more actually 4 causes that cause genetic variety even though mainstream high school Biology only discusses the three main ones: Crossing over, independent assortment (which happen during sexual reproduction), and, random genetic mutations.
The 4th one is gene transfer. Species transfer genes between them.
What else can I help you with?
What two different sources of genetic variation in a plant or animal population?
The main source of genetic variation is a large population with a large gene pool.
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.
Other sources of genetic variation in a population are?
Other sources of genetic variation in a population include genetic mutations, genetic recombination during sexual reproduction, and gene flow from migration of individuals between populations. These processes can introduce new genetic combinations and alleles into the population, leading to increased genetic diversity.
What is the signifiance of the genetic variation and natural selection?
Genetic variation is important because it allows for diversity within a population, which increases the chances of survival in changing environments. Natural selection acts on this variation, favoring traits that increase an organism's fitness and leading to adaptation and evolution over time.
Which of these is necessary for natural selection to occur genetic engeneering genetic variation asexual reproduction or enviormental stability?
Genetic variation is necessary for natural selection to occur. This variation provides the raw material for differential survival and reproduction, which drives the process of natural selection. Without genetic variation, there would be no differences for natural selection to act upon.
What are two sources of genetic variation?
Natural and Artificial Selection
What are the two main sources of genetic variation and which of them is more common?
The two main sources of genetic variation are sexual reproduction, and mutation. Sexual reproduction is more common.
What are sources of genetic variation in sexually - reproducing organisms?
meiosisHuman recombination
What are the sources of genetic variation in plants and each of the major pathogen groups?
mutation
What two different sources of genetic variation in a plant or animal population?
The main source of genetic variation is a large population with a large gene pool.
What are two main sources for genetic variation in a population?
Mutation and recombination are the two main sources of genetic variation in a population. Mutations are changes in the DNA sequence, while recombination occurs through the mixing of genetic material during the formation of gametes.
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.
Other sources of genetic variation in a population are?
Other sources of genetic variation in a population include genetic mutations, genetic recombination during sexual reproduction, and gene flow from migration of individuals between populations. These processes can introduce new genetic combinations and alleles into the population, leading to increased genetic diversity.
What is One consequence of genetic drift is?
Loss of genetic variation(:Novanet:)
Mutations and the genetic shuffling that occur during sexual reproduction are both sources of?
Genetic variation. Mutations introduce new genetic changes that can be passed on to offspring, while genetic shuffling during sexual reproduction mixes genetic material from two parents to create unique combinations of genes in the offspring.
What are some sources of variations?
Some sources of variation include genetic differences, environmental factors, random mutations, and genetic recombination during sexual reproduction. These variations contribute to the diversity of traits and characteristics within a population.
What are the two main of genetic variation?
The two main sources of genetic variation are mutations, which are changes in the DNA sequence, and recombination, which occurs during meiosis when genetic material is exchanged between homologous chromosomes. These processes contribute to genetic diversity within populations.
