Does random alignment of chromosomes during Meiosis produce genetic variations?
Wiki User
∙ 13y ago
In meiosis crossing over may occur at certain points on a chromatid. Crossing over is where variation occurs in allele combination. When a Zygote is formed alleles from mother and father cross over.. this is why you may have some features resembling your father and your mother... or grandma or grandpa... etc...
There can be mutations ( messups ) in mitosis but the actual process results in no genetic variation.

What leads to genetic variation in a population?
Random mutations in an organism's DNA after reproduction.what lead to variations
What causes genetic variation in a species?
genetic variation happens because of meiosis. chromosomes are randomly in each sperm/egg cell, and so when they come together it's unlikely to get the same combination twice
How do mutation and crossing over cause genetic variation?
In meiosis I, segregation of chromosomes...that is, separating off into pairs, allows for crossing over to occur. Crossing over is one mechanism responsible for gene recombination to occur, and genetic recombination is one way that variations in traits increase.
Where is genetic information in the nucleus stored?
Genetic information is stored in the chromosomes.
Which is responsible for genetic variation mitosis or meiosis?
Meiosis is responsible for genetic variation
Random alignment of chromosomes contribute to genetic variation?
Random alignment of chromosomes occurs during Metaphase I in a cells meiosis. Random alignment is when the homologous pairs of chromosomes line up at the equator or middle of the cell, and are arranged by which member faces what pole. This allows equal opportunity for the chromosomes to migrate to a different cell.
What is a source of genetic variation that involves the swapping of sections of chromosomes during meiosis.?
What is a source of genetic variation that involves the swapping of sections of chromosomes during meiosis.?
What is the reshuffling of chromosomes during meiosis?
genetic recombination
When Homologous chromosomes swap genetic information as part of meiosis?
Prophase I is the phase of meiosis.
Chromosomes exchange genetic information through the process of what?
Chromosomes exchange genetic information during a process called crossing over. This occurs during meiosis
What causes genetic variations in humans?
meiosis... for example.. crossing over
Which statement best explains the significance of meiosis in the process of evolution within species?
Meiosis takes place in sexual reproduction and genetic variations takes place in sexual reproduction. Genetic variations lead to evolution to new species.
What factors contribute to genetic diversity?
The way the chromosomes line up during meiosis.
Is a source of genetic variation that involves the swapping of sections of chromosomes during meiosis.?

What is swapping of genetic material between homologous chromosomes?
Swapping of genetic genetic material is when two chromosomes (maternal and paternal) with the same gene sequence exchange genes, this occurs during Phrophase 1 of meiosis by a process called crossing over. Hope this helps.
What are the three outcomes of meiosis?
Three outcomes of meiosis: it reduces chromosomes to the haploid number, it provides genetic variation, and it ensures the correct distribution of chromosomes into the resulting cells.
What is a source of genetic variation that involves the swapping of sections of chromosomes during meiosis?
Crossing Over.
