Four gametes are possible from a single diploid cell that undergoes meiosis. This is because meiosis involves two rounds of cell division, resulting in four haploid daughter cells with a unique combination of genetic material.
A gamete is haploid (1N) so 'Aa' & 'AA' are diploid and during cell division (mitosis) gametes are formed and then 2 gametes merge together to make a diploid (think of sperm and egg, each is haploid or 1N, when fertilization occurs the egg and sperm form 1 cell that is 2N or diploid). So the possible gametes for 'Aa' would be 'A' & 'a' while for 'AA' the only gametes possible are 'A' If the question is asking what the possible gametes are for 'AaBB' the haploid (gamete) can be 'AB' or 'aB'
Fertilization of gametes produces a diploid cell called a zygote. This occurs when the haploid sperm and egg fuse to form a new organism with a full set of chromosomes.
Gametes are haploid cells because they only contain half of the chromosomes of a diploid cell. For example, a human somatic (diploid) cell contains 46 chromosomes. Therefore, a haploid cell contains 23 chromosomes.
the zygote
No, a zygote is a diploid because it has the full number of 46 (23pairs) of chromosomes. Two gametes one from the male one from the female meet to form a zygote. gametes = haploid everything else = diploid
The haploid number (n) is the number of chromosomes in a gamete of an individual. This is distinct from the monoploid number (x), which is the number of unique chromosomes in a single complete set. Gametes (sperm, and ova) are haploid cells. The haploid gametes produced by (most) diploid organisms are monoploid, and these can combine to form a diploid zygote. For example, most animals are diploid and produce monoploid gametes.
The diploid cell type is the somatic cell. Gametes, such as ovum, are haploid cells that are produced by the process of meiosis from diploid germ cells.
Meiosis in simple terms is the process by which gametes (sperm and egg) fuse together to produce a fertilised egg. Haploid is a word that refers to how many chromosomes a certain cell has. In this case the gametes have a haploid number of chromosomes, which is half the number a normal cell has. A normal cell has a diploid number of chromosomes. So in meiosis the two gametes come together with their hapoid number of chromosomes each to create an egg that has a diploid (standard) number of chromosomes.
A haploid cell contains a single set of chromosomes (half the normal number), typically found in gametes (sperm and egg cells). In contrast, a diploid cell contains two complete sets of chromosomes, one from each parent, and is found in most somatic cells of the body.
The steps in the diploid life cycle are meiosis, to gametes, to fertilization, to diploid, to reproductive cell. The main steps are Meiosis and Fertilization.
A cell such as a somatic cell that contains two sets of chromosomes is said to be a diploid.
