Which type of reproduction produces more genetic variation?
Sexual reproduction Sexual reproduction provides genetic diversity because the sperm and egg that are produced contain different combinations of genes than the parent organisms. Asexual reproduction, on the other hand, does not need sperm and eggs since one organism splits into two organisms that have the same combination of genes.
Which type of reproduction produces offspring with more genetic variation quizlet?
Sexual reproduction increases variation among offspring because the sperm and egg have different combinations of genes than their parent organisms.
Which produces more genetic variation in offspring mitosis or meiosis?
Apart from this reduction in chromosome number, meiosis differs from mitosis in yet another way. Specifically, meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes.
Does asexual reproduction increase genetic variation?
Asexual reproduction involves only one parent with little or no genetic variation, while sexual reproduction involves two parents who contribute some of their own genetic makeup to the offspring, thus creating a unique genetic being.
Does asexual reproduction increase genetic diversity?
And not only does asexual reproduction lead to higher rates of genetic diversity, it also is two times more efficient than sexual reproduction.
What is asexual reproduction also called?
Asexual reproduction is also known as Agamogamy/Agmogenesis/Somatogenic reproduction as it does not involve the formation and fusion of gametes.
Which of the following contributes to genetic variation?
Which of the following contribute to genetic diversity? Explanation: Meiosis, which includes independent assortment of homologous chromosomes and chromosomal crossover, contributes to genetic diversity.
Which reproduction is also known as vegetative reproduction?
asexual reproduction Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules.
What is asexual fission?
binary fission, asexual reproduction by a separation of the body into two new bodies. In the process of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA.
Which species have the highest genetic variation?
The split gill mushroom (Schizophyllum commune) has a nucleotide diversity of up to 20%, according to a 2015 study published in the journal Molecular Biology and Evolution. According to the study, that's the greatest genetic diversity reported for any eukaryote, or organism whose cells have a nucleus.

What is the difference between vegetative reproduction and asexual reproduction?
Asexual reproduction is a type of reproduction where only one parent is involved. The offspring produced is identical to the parent morphologically and genetically. Vegetative propagation is a type of asexual reproduction, wherein a new plant is produced from the vegetative parts of a plant.
What is called binary fission?
binary fission, asexual reproduction by a separation of the body into two new bodies. In the process of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA.
What type of reproduction is budding?
budding, in biology, a form of asexual reproduction in which a new individual develops from some generative anatomical point of the parent organism. In some species buds may be produced from almost any point of the body, but in many cases budding is restricted to specialized areas.
Where is the most genetic variation found?
Anatomically modern humans probably originated in Africa, undergoing population bottlenecks as some left to colonize the rest of the world. Because these events are fairly recent, and because of extensive gene flow within major human populations, most genetic variation can be found within major human populations.
Which process contributes to the greatest genetic diversity?
Meiosis Meiosis introduces genetic variations by crossing over and random fusion of these genetically diverse gametes imparts additional genetic diversity to the offspring. So, the correct answer is option B.
Which processes increase genetic variation?
Genetic variation is increased by meiosis Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase I.
Does asexual reproduction have genetic variation?
Asexual reproduction involves only one parent with little or no genetic variation, while sexual reproduction involves two parents who contribute some of their own genetic makeup to the offspring, thus creating a unique genetic being.
What is the difference between binary fission and multiple fission?
Binary fission: binary fission is the spliting or division of a cell into two daughter cells. Multiple fission: multiple fission is the division or spliting of a parent cell into two or more daughter cells.
What is the difference between fragmentation and spore formation?
Fragmentation occurs when the parent is matured enough. Fungus like bread mould reproduces asexually by spore formation. Spores (present in the air) are small spherical bodies that has a thick protective coat which protects it from unfavourable conditions.
What is the difference between binary fission and mitosis?
Binary fission and mitosis are both forms of asexual reproduction in which a parent cell divides to form two identical daughter cells. Binary fission occurs primarily in prokaryotes (bacteria), while mitosis only occurs in eukaryotes (e.g., plant and animal cells).
What type of reproduction is parthenogenesis?
True parthenogenesis (Greek for “virgin birth”) is a form of asexual reproduction in which the production of offspring occurs in the absence of any male genetic contribution. Females produce unfertilized eggs that will develop into viable embryos (Neaves and Baumann, 2011).
What type of reproduction is fragmentation?
One of the known asexual reproduction types is known by the name 'fragmentation'. As the name is quite self-explanatory, it is a type of cloning where one organism is divided into minor fragments. Once divided, these fragments develop into individual ones which are fully grown.
Which group has the most genetic variation quizlet?
The most human genetic variation and diversity exists in African populations which shows striking agreement with fossil evidence.
Which of the following would increase genetic variation?
Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation. New genetic variation can be created within generations in a population, so a population with rapid reproduction rates will probably have high genetic variation.
Does mitosis contribute to genetic variation?
1 Answer. Meiosis creates more genetic variation. This is because it produces 4 daughter cells, none of which are genetically identical, while mitosis produces 2 identical daughter cells (which are identical to the parent cell).
Which process most contributes to genetic variation in a population?
It is the specific process of meiosis, resulting in four unique haploid cells, that results in these many combinations. This independent assortment, in which the chromosome inherited from either the father or mother can sort into any gamete, produces the potential for tremendous genetic variation.
Does asexual reproduction produce more variation?
Asexual reproduction involves only one parent with little or no genetic variation, while sexual reproduction involves two parents who contribute some of their own genetic makeup to the offspring, thus creating a unique genetic being.
Does asexual reproduction produce more offspring?
With asexual reproduction you get two times as many offspring and two times as many genes into the population." There is a broad assumption in this scenario that males do not help with the care and feeding of offspring, although in a small proportion of species they do help: people, wolves, foxes and most songbirds.
What is the difference between fission and fragmentation?
The main difference between fission and fragmentation is that in fission, a unicellular organism breaks up to form two daughter organisms whereas in fragmentation, a multicellular organism breaks up into various fragments and each fragment develops into a complete organism.
