Black rat, and like 8 others but black rats don't always have 46.
23 i think -- There's no such thing as "a DNA. But it works the other way around: DNA doesn't contain chromosomes, but chromosomes contain DNA. A person has 23 chromosome pairs: 46 chromosomes. One (pair) of which decides gender. Some people aren't perfect and have 47 chromosomes. Maybe other 'combinations' exist too.
It varies from species to species in human there are 46 chromosomes (23 pairs)
46...same as any other somatic cell in the body
In humans, each body cell typically has 46 chromosomes, arranged in 23 pairs. This includes 22 pairs of autosomes and one pair of sex chromosomes. The number can vary in other species, but for humans, 46 is the standard count in somatic cells.
A spermatid contains 23 chromosomes, which are the result of meiosis dividing the original diploid germ cell's 46 chromosomes in half. This reduction in chromosome number ensures that when the spermatid fuses with an egg during fertilization, the resulting zygote will have the correct number of chromosomes.
Only Zygotes of certain species have 46 chromosomes.
46 Chromosomes
It varies from species to species. The human nucleus contains 46 chromosomes.
Like any other cell it has 46.
No, different species have different numbers of chromosomes. Humans have 46 chromosomes, dogs have 78 chromosomes, and horses have 64 chromosomes, for example. The number of chromosomes in a species typically remains constant within that species.

Most organisms have a specific number of chromosomes that is characteristic for their species. For example, humans typically have 46 chromosomes (23 pairs), while dogs have 78 chromosomes (39 pairs). However, the number of chromosomes can vary among different species.

Same as any other somatic cell - 46.

The same as in any other human autosomal cell, 46.
