Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 1, one copy inherited from each parent, form one of the pairs.

Each of the three haploid nuclei in the germinated pollen grain must contain 12 chromosomes, and each of the 8 nuclei within the embryo sac contain 12 chromosmes. A triploid endosperm cell inside a seed must contain 36 chromosomes (3 x 12 = 36).

A frog gamete has 13 chromosomes. Every frog body cell, then, has 26 chromosomes.

A quick overview of cell division The genetic information of plants, animals and other eukaryotic organisms resides in several (or many) individual DNA molecules, or chromosomes. For example, each human cell possesses 46 chromosomes, while each cell of an onion possesses 8 chromosomes.

Spermatids have half this number, for a total of 23 chromosomes. Each chromosome is composed of only a single chromatid following division, for a total of 23 chromatids. When the zygote is formed during the fusion of the sperm and egg cells, the final cell is diploid, containing 46 chromosomes (23 from each gamete).

Question: Humans Have 46 Chromosomes In Their Kidney Cells.
193707
Humans have 23 pairs of chromosomes, for a total of 46 chromosomes. In fact, each species of plants and animals has a set number of chromosomes. A fruit fly, for example, has four pairs of chromosomes, while a rice plant has 12 and a dog, 39.
455109
Some insects, for instance, only have one or two chromosomes. Meanwhile, giraffes have 62, chickens have 78, mice have 40, cabbages 18, and strawberries only 14. Humans, like many other species, are called 'diploid'.
265713
In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Monkeys, chimpanzees, and Apes have 24 pairs (twenty-four pairs), for a total of 48.
