Does meiosis use normal body cells to produce gametes?
No, meiosis does not use normal body cells to produce gametes. Meiosis is a specialized type of cell division that occurs in the reproductive organs to produce gametes (sperm and egg cells) with half the number of chromosomes as a normal body cell.
The cells that will eventually undergo meiosis to produce gametes are what?
These cells are called germ cells. They go through the process of meiosis to produce gametes (sperm or eggs) with half the normal number of chromosomes.
What is a viable embryo?
A viable embryo is an embryo that has the potential to develop into a healthy offspring under normal conditions. This typically means it has successfully reached a developmental stage where it can be transferred or implanted into a uterus to continue its growth into a fetus.
In a normal pregnancy the embryo becomes attached to the?
In a normal pregnancy the embryo becomes attached to the
How many chromosome' s do people have in their gametes?
People have 23 chromosomes in their gametes – 22 autosomes and one sex chromosome. This is the result of a process called meiosis, which halves the number of chromosomes in a cell to produce gametes with half the genetic material.
What are the main functions of meiosis?
The main function of meiosis is to produce gametes, which are the egg and sperm cells. These cells have half of the number of chromosomes that are in a normal body cells.
When a cell with half the normal number of chromosomes is generated during meiosis how can it eventually produce cells with the normal number of chromosomes?
During meiosis, a cell with half the normal number of chromosomes (haploid) is generated to eventually form gametes (sperm or egg). When two haploid gametes fuse during fertilization, they restore the full set of chromosomes (diploid) in the zygote. This zygote then undergoes mitotic cell divisions to produce cells with the normal number of chromosomes.
How many chromosomes are in a normal persons gametes?
23
Process by which the number of chromosomes per cell is cut half used by organisms to produce gametes?
Meiosis takes a cell from 2N (Diploid) to N (haploid) and produces 4 daughter cells at 23 chromosomes. These are the sex gametes. A normal 2N cell would have 46 chromosomes.
Is it normal if there is a sac but no baby at 6wks and ovary swelling?
I am afraid it is unlikely. Ovary swelling is normal as cells in the sac the egg came from grow to provide hormones to maintain a pregnancy but if there is no embryo in the sac you have what is called a blighted ovum which cannot develop into a baby.
Does oogenesis involve meiosis?
Yes, oogenesis involves meiosis. In this process, a diploid cell undergoes two rounds of cell division to produce haploid eggs, which have half the number of chromosomes as the original cell.
What happens if the gametes aren't haploid?
The whole purpose of reducing the gamete to contain half the number of normal chromosomes is so that normal chromosome numbers can be achieved again when the gametes fuse to form a zygote. If the gamete is not halved, polyploidy results. This is a generic term to describe having more than the normal number of chromosomes.
