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.
What would happen if human sperm and eggs were produced by mitosis explain why this would result in an embryo which had double the normal number of chromosomes in each cell?
What would happen if human sperm and eggs were produced by mitosis? Explain why this would result in an embryo which had double the normal number of chromosomes in each cell. A human embryo with that many chromosomes in each cell would be abnormal and would die before it could develop into a baby.
Why can’t mitosis make sperm or egg?
Why can’t your body use mitosis to make sperm or eggs? To produce the needed number of chromosomes in sperm and eggs, meiosis reduces the number of chromosomes by half.
What would happen if humans reproduced using mitosis?
Mitosis copies a cell and its DNA so the child’s DNA would be identical to the parents and they would look exactly alike. It would be like a lot of twins walking around. That is assuming there are no mutations in the mitosis process.
What would happen if sperm and egg cells were accidentally diploid?
explain what would happen if sperm and egg cells were accidentally diploid. If the gametes were not haploid, then the fertilized zygote would have four sets of chromosomes and would probablydie before birth.
Why can’t humans reproduce using mitosis?
Mitosis results in identical cells that have the same number of chromosomes as the original cell. When the process starts, the genetic material is duplicated into two chromotids. … Since the daughter cells have all the genetic material of the original, they cannot be used for sexual reproduction.
Why are there two sets of phases in meiosis?
Answer: Cells undergoing mitosis just divide once because they are forming two new genetically identical cells where as in meiosis cells require two sets of divisions because they need to make the cell a haploid cell which only has half of the total number of chromosomes.
Can mitosis ever be used for human reproduction?
In single-cell organisms, mitosis is the only form of cellular reproduction. One round of mitosis yields two genetically identical cells. … This is classified as asexual reproduction because it does not require sex for the creation of new organisms.
Do eggs go through mitosis?
Egg production takes place in the ovaries. It takes several steps to make an egg: Before birth, special cells in the ovaries go through mitosis (cell division), producing identical cells. … They go through the second stage of cell division after the female goes through puberty.
What would happen if interphase didn’t occur first?
What would happen if interphase didn’t occur first? The cell wouldn’t grow to it’s full size and it would not replicate its DNA. Meiosis does not always occur without any difficulties. Describe what occurs during nondisjunction and the effect on resulting cells.
What would happen if humans used mitosis instead of meiosis?
What would happen if gametes were made by mitosis instead of meiosis? Explanation: … During fertilization of diploid gametes, the zygote would become 4n=92. With each new generation the number of chromosomes would double.
Why is meiosis called reduction division?
Meiosis is sometimes called “reduction division” because it reduces the number of chromosomes to half the normal number so that, when fusion of sperm and egg occurs, baby will have the correct number. … In this example, a diploid body cell contains 2n = 4 chromosomes, 2 from mom and two from dad.
How many chromosomes would the cells have after four generations without meiosis?
Answer: it will be 64 chromosomes after four generations.
