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.
What would be the result of fertilization if egg and sperm were produced by mitosis rather than meiosis?
Question: Question 1 What would be the result of fertilization if egg and sperm were produced by mitosis rather than meiosis? The resulting offspring would have twice as much DNA as the parents. … The resulting offspring would have half the amount of DNA as the parents.
What would be the result of using mitosis to produce sperm and eggs?
Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. … When the sperm and egg cells unite at conception, each contributes 23 chromosomes so the resulting embryo will have the usual 46.
Is fertilization a result of 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.
What would the ploidy of the zygote be if egg and sperm were produced by mitosis rather than meiosis How would this affect the ploidy of each successive generation?
What would the ploidy of the zygote be if the egg and sperm were produced by mitosis rather than meiosis? How would this affect the ploidy of each successive generation? the ploidy of the zygote would be genetically identical to the parent cells.
Which of these is produced as a result of fertilization?
The result of fertilization is a cell (zygote) capable of undergoing cell division to form a new individual.
What would happen if we produce diploid eggs and sperm?
If the sperm and eggs of a diploid species such as humans were produced by mitosis, these reproductive cells would be diploid as well. Fertilization…
Why is crossing over important?
This process, also known as crossing over, creates gametes that contain new combinations of genes, which helps maximize the genetic diversity of any offspring that result from the eventual union of two gametes during sexual reproduction.
What is the result of mitosis?
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
What would happen if humans produces reproductive cells through mitosis?
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. With each new generation the number of chromosomes would double.
What problem would result if gametes were diploid?
Answer: If gametes were diploid, the resulting organism would have too many chromosomes.
What happens to the two cells formed at the end of meiosis 1 Choose two correct answers?
Meiosis I ends when the chromosomes of each homologous pair arrive at opposing poles of the cell. The microtubules disintegrate, and a new nuclear membrane forms around each haploid set of chromosomes. The chromosomes uncoil, forming chromatin again, and cytokinesis occurs, forming two non-identical daughter cells.
