What would happen if gametes were made by mitosis instead of meiosis? Explanation: … If gametes were produced instead by mitosis each gamete would be diploid not haploid. During fertilization of diploid gametes, the zygote would become 4n=92.
Why would a germ cell divide by meiosis and not mitosis?
Because the chromosome number of a species remains the same from one generation to the next, the chromosome number of germ cells must be reduced by half during meiosis. To accomplish this feat, meiosis, unlike mitosis, involves a single round of DNA replication followed by two rounds of cell division (Figure 1).
What happens when germ cells undergo mitosis?
Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg). The development of a new progeny organism is then initiated by the fusion of these gametes at fertilization.
How would children look if humans would reproduce through mitosis instead of using meiosis would there be any pitfalls in a population of humans if mitosis were the primary method for reproduction?
Children would be identical to their parents. Mitosis copies a cell and its DNA so the child’s DNA would be identical to the parents and they would look exactly alike. … That is assuming there are no mutations in the mitosis process.
How does human life depend on mitosis?
Replacement and regeneration of new cells– Regeneration and replacement of worn-out and damaged tissues is a very important function of mitosis in living organisms. Mitosis helps in the production of identical copies of cells and thus helps in repairing the damaged tissue or replacing the worn-out cells.
What happens during meiosis that does not happen during mitosis?
The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred. The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads.
How many chromosomes would the cells have after four generations without meiosis?
Answer: it will be 64 chromosomes after four generations.
What would the ploidy of the zygote be if egg and sperm were produced by mitosis rather than meiosis?
What would the ploidy of the zygote be if egg and sperm were produced by mitosis rather than meiosis? … The ploidy of the zygote would be genetically identical to the parent cells. Since mitosis doesn’t reduce the number of chromosomes by half, each successive generation would have twice as many chromosomes as the last.
