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'
diploid
no, gametes are 1/4 of a diploid cell.
Every cell in the human body (excluding gametes) is a diploid cell.
the zygote
23 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 steps in the diploid life cycle are meiosis, to gametes, to fertilization, to diploid, to reproductive cell. The main steps are Meiosis and Fertilization.
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.
When two gametes fuse during sexual reproduction, the single cell that forms is called a zygote. The gametes each have one set of chromosomes and are said to be haploid. When they fuse, they form the first diploid cell of the offspring, the zygote, which has two sets of chromosomes.
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
A cell such as a somatic cell that contains two sets of chromosomes is said to be a diploid.
