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 else can I help you with?
When parts of chromosomes are broken off and lost during mitosis or meiosis the result is an?
when parts of chromosomes are broken off and lost during mitosis the results is a chromosomal mutation
During meiosis crossing-over gene exchange between chromosomes may occur Crossing-over usually results in?
The result of crossing over is genetic diversity. More specifically, it is a hybrid chromosome with a unique pattern of genetic material. Does this answer help?
How does variation occur?
Variation or mutation occurs within the DNA. It is a natural result of the replication process, or the copying of one DNA strand to make new DNA during reproduction. If the new mutation ends up making some kind of variation that does not kill the organism, then the variation will be passed on to new generations. This is how new traits are formed. When the variation is actually more useful than a trait that the organism's parents had, that new variation will be passed along as a survival trait.
A change in the genetic material that produces variation in a species may be the result of?
immigration, mutation and sexual reproduction.
What causes many endangered species that are now found only in zoos to have very little genetic variations?
Founder effect refers to the loss of genetic variation when a new colony is established by a very small number of individuals from a larger population. As a result of the loss of genetic variation, the new population may be distinctively different.Bottleneck effect is an evolutionary event in which a significant percentage of a population or species is killed or otherwise prevented from reproducing, and the population is reduced by 50% or more, often by several orders of magnitude.Population bottlenecks increase genetic drift, as the rate of drift is inversely proportional to the population size.They also increase inbreeding due to the reduced pool of possible mates.
Why are mitosis and mitosis similar?
Because they both result in the formantion of gametes; however there is no genetic variation in meiosis.
Why meiosis 2 is similar to mitosis?
Because they both result in the formantion of gametes; however there is no genetic variation in meiosis.
Where do you expect genetic differences between cells to arise from mitosis or from meiosis?
That is a good question. In mitosis, you don't get regular genetic variation but chance mutations can occur. In meiosis with fertilization, you get pairing of DNA from different hosts on a regular basis. I would choose the latter.
Genetic variation in bacterial populations cannot result from?
Genetic variation in bacterial populations cannot result from sexual reproduction, as bacteria typically reproduce asexually by binary fission.
What is the result of meiosis in terms of genetic variation and the formation of haploid cells?
The result of meiosis is the formation of haploid cells with genetic variation. Meiosis creates four haploid cells, each with a unique combination of genetic material due to processes like crossing over and independent assortment.
What kind of impact does crossing over create in genetic variation during meiosis?
Crossing over during meiosis creates genetic variation by exchanging genetic material between homologous chromosomes, leading to new combinations of genes in offspring. This increases genetic diversity and can result in unique traits in individuals.
Why is variation not possible in mitotic division of cells?
Mitosis does not lead to the formation of chromosomes with new combination. In meiosis as a result of crossing over, chromosomes with new combinations are formed which are responsible for variation.
Does meiosis have variation?
Yes, meiosis results in genetic variation due to processes such as crossing over (exchange of genetic material between homologous chromosomes) and random assortment of chromosomes. These mechanisms contribute to the unique combinations of maternal and paternal genes in the resulting gametes.
Which type of reproduction results in the greatest amount of genetic variation?
That would be sexual reproduction. Sexual reproduction allows for independent assortment and crossing over to occur. This is fancy language for the genetic material gets mixed up a lot. Since the genetic material gets mixed up, variation will result.
Why are meiosis and mitosis similar?
Meiosis and mitosis are both processes involved in cell division. They both include stages such as prophase, metaphase, anaphase, and telophase. However, meiosis involves two divisions resulting in four genetically unique haploid cells, while mitosis involves one division resulting in two genetically identical diploid cells.
Which is responsible for most genotypic and phenotypic variation among humans 1 meiosis 2 budding 3 mitosis or 4 regeneration?
Meiosis is responsible for most genotypic and phenotypic variation among humans because it produces haploid gametes with unique combinations of parental genes through crossing over and independent assortment during prophase I.
Does chiasmata occur in mitosis?
No, chiasmata do not occur in mitosis. Chiasmata are structures that form during meiosis, specifically during prophase I, as a result of crossing over between homologous chromosomes. Mitosis does not involve homologous chromosomes pairing up and exchanging genetic material like in meiosis.
