Randomly and naturally occuring mutation. A virus might also inject some DNA into their spores or something as well.
Bacteria take in DNA fragments from their environments.
Bacterias do not reproduce sexually.
They belongs to kingdom mamalia and reproduce sexually
Plants and algae can reproduce sexually by releasing gametes that fuse to form a zygote, or asexually through methods like fragmentation or spore formation. In certain algae species, alternation of generations can occur, where both sexual and asexual reproduction methods are utilized to complete the life cycle.
Sponges can reproduce sexually or asexually. They can reproduce through producing eggs and sperm that are released into the water where they can combine to form larvae. Asexual reproduction can occur through budding, fragmentation, or producing gemmules.
A variation in characteristics within populations of the same species is called intraspecific variation. This variation can occur due to genetic differences, environmental factors, and developmental processes, leading to diverse traits among individuals in the same species. Understanding intraspecific variation is crucial for studying evolution, ecology, and conservation.
Yes, corals can reproduce sexually through a process called spawning. During spawning, corals release eggs and sperm into the water simultaneously, allowing fertilization to occur externally. This process leads to the formation of new coral colonies.
Both!The foraminiferal life-cycle involves an alternation between haploid and diploidgenerations where multiple rounds of asexual reproduction between sexual generation.
If meiosis did not occur then the chromosome number would double each generation, and the cell could not survive with this increasingly larger number of chromosomes.
Angiosperms reproduce sexually through the process of pollination, where pollen is transferred from the male reproductive organ to the female reproductive organ. Asexual reproduction in angiosperms can occur through processes such as vegetative propagation, where new plants are produced from vegetative structures like roots, stems, or leaves without the involvement of seeds or spores.
Coelenterates, such as jellyfish and corals, reproduce both sexually and asexually. In sexual reproduction, they often release sperm and eggs into the water, leading to external fertilization. Asexual reproduction can occur through budding, where new individuals grow from the parent organism, or through fragmentation. The specific method can vary among different coelenterate species.
Organisms that reproduce asexually, such as certain bacteria, archaea, and some plants and fungi, typically exhibit little to no genetic variation. This is because they replicate their genetic material without the process of meiosis, leading to offspring that are genetically identical to the parent. However, mutations can still occur, introducing some level of variation over time. In contrast, sexually reproducing organisms tend to have greater genetic diversity due to the mixing of parental genes.
Goldfish reproduce sexually, meaning they require both a male and a female to fertilize eggs. The male releases sperm near the eggs laid by the female for fertilization to occur.
