Why does variation occurs when a single cell divides into two cells?
Variation can occur during cell division due to errors in the replication of DNA or random mutations. These errors can lead to changes in the genetic material of the cells, resulting in variations in the offspring cells. Additionally, environmental factors or external influences can also contribute to variations during cell division.
What does two daughter cells with different DNA represent?
Two daughter cells with different DNA may represent a mutation or an error during cell division. This can lead to genetic variation and potentially cause abnormalities or changes in the characteristics of the cells.
What is the result of incomplete cellular division?
Incomplete cellular division can lead to the formation of cell fragments or abnormal cells with abnormal chromosome numbers, which can result in genetic abnormalities or cell death. This can lead to impaired tissue function and potentially contribute to the development of diseases such as cancer.
Genetic variation occurs when chromosomes are shuffled in and fertilization?
Genetic variation is primarily a result of two main processes: crossing over during meiosis, which shuffles the genetic material on homologous chromosomes, and fertilization, which combines the genetic material from two different individuals. These processes lead to the creation of offspring with unique combinations of genetic information.
What would happen to the chromosomes in each cell if copies of them were not made before cell division?
There would be no life
How are mutations random in the process of genetic variation?
Mutations are random changes in the DNA sequence that can occur during cell division or due to external factors like radiation or chemicals. These changes can lead to genetic variation by altering the instructions for making proteins, which can result in different traits or characteristics in an organism.

Two daughter cells with different DNA may represent a mutation or an error during cell division. This can lead to genetic variation and potentially cause abnormalities or changes in the characteristics of the cells.
If a cell's DNA were not copied before cell division the cell could?
If a cell's DNA is not copied before division, the new daughter cells would have incomplete or incorrect genetic information, leading to potential mutations, genetic abnormalities, or cell death. This can result in improper functioning of the cells and potentially lead to diseases or defects.
Why does meiosis lead to significant genetic variational mitosis does not?
Meosis is a process of cell division where a diplod cell becomes four haploid cells resembling mitosis but the chromosomes are duplicated once in which gametocytes form gametes.They occur in genetic information in variation of female and male gametes. In mitosis the nuclei of the diplod cells reproduce after chromosomes duplicate in four stages with two diploid cells formed with identical set of chromosomes with the cytoplasm also divides with the cells. They occur in somatic cells.
Mutations are a source of what in a species?
Genetic variation, which can lead to evoloution, and then potentially a new species.
What would happen if the sister chromatids failed to separate during cell division"?
If sister chromatids fail to separate during cell division, it can lead to an abnormal number of chromosomes in the daughter cells, which can result in genetic disorders or cell death.
What is the result of incomplete cellular division?
Incomplete cellular division can lead to the formation of cell fragments or abnormal cells with abnormal chromosome numbers, which can result in genetic abnormalities or cell death. This can lead to impaired tissue function and potentially contribute to the development of diseases such as cancer.
Are mutations a significant source of genetic variation?
Yes, mutations are a significant source of genetic variation as they introduce new genetic changes that can lead to differences in traits among individuals within a population.
Is a mutation passed on to new cells that are copied by it?
Yes, mutations are passed on to new cells during replication. If a mutation occurs in a cell's DNA, it will be present in all daughter cells that are produced through replication. This can lead to genetic variation and evolution over time.
What leads to genetic variation in a population?
Random mutations in an organism's DNA after reproduction.what lead to variations
What would decrease genetic variation in a population?
Inbreeding, genetic drift, and natural selection can decrease genetic variation in a population by reducing the number of different alleles present. These processes can lead to a loss of genetic diversity and increase the prevalence of certain genetic traits within the population.
