how many chromosomes do sharks have?
235258
The great white shark genome—like the animal itself—is giant, with 41 pairs of chromosomes compared to humans' 23 pairs, researchers reported yesterday (January 18) in PNAS.

Chromosomes ensure that DNA is evenly distributed and are accurately copied during cell division. How many chromosomes does a dog have? Each cell in a dog's body contains 39 pairs of chromosomes.

How many pairs of chromosomes do dogs have in their somatic cells? Dogs have 39 pairs of chromosomes in their somatic cells. 3. Horses have 16 chromosomes in their haploid cells.

Number. Domestic cats have 38 chromosomes, as compared to 46 in humans. The chromosomes come in 19 matched pairs, with one of each pair coming from each parent.
81574
Each pair of chromosomes comprises one chromosome inherited from the father and one inherited from the mother. For example, in humans, somatic cells contain 46 chromosomes organized into 23 pairs. By contrast, gametes of diploid organisms contain only half as many chromosomes.

Although, the base of the scales are living cells and they have 24 chromosomes. In the normal conditions, the male and female gametes unite to form the zygote which is the first stage of an organism. The sperm of the fish with 12 chromosomes indicates haploid number of chromosomes.

The haploid zebrafish genome has 25 chromosomes, most of which are difficult to distinguish. These chromosomes contain about 1.7 X l09 base pairs of DNA, about half the mammalian genome size.

Dogs have 39 pairs of chromosomes in their somatic cells. 3. Horses have 16 chromosomes in their haploid cells.

The basic construction of chromosomes (made of chromatin) and structure (long but scrunched up) is the same in all animals. The difference is that each species has its own set number of chromosomes. For instance, all human cells (except gametes) have 46 chromosomes.

Killer whales have 44 chromosomes; an excellent banding study was done on six killer whales that showed considerable polymorphism of C-bands; this is shown in the following picture (Arnason et al., 1980).

The vast majority of snakes have diploid numbers (2n) of 36 chromosomes, containing 16 macrochromosomes and 20 microchromosomes [19,20].

An elephant has 56 chromosomes in its somatic cells, a diploid number. An elephant's liver cell also has 56 chromosomes since it is a somatic cell. This means that an elephant has 28 pairs of chromosomes in contrast to humans who have only 23 pairs.

Each body cell of a chimpanzee contains 48 chromosomes. How many chromosomes would normally be present in a gamete produced by this chimpanzee? 14. The normal diploid chromosome number of the house mouse, Mus musculus, is 40.

The number of chromosomes is reduced from 46 (23 pairs) to 23 during the process of meiosis. Because they have only half the total chromosomes in a somatic cell, they are termed haploid (n). In a human egg or sperm, there are 23 chromosomes, one of which is an X or Y.

Humans have 46 chromosomes, whereas chimpanzee, gorilla, and orangutan have 48. This major karyotypic difference was caused by the fusion of two ancestral chromosomes to form human chromosome 2 and subsequent inactivation of one of the two original centromeres (Yunis and Prakash 1982).

As chromosome number in cat is 38 i.e. 2n = 38. So, all the somatic cells of cat will have 38 chromosomes while the gametes will have half i.e. 19 chromosomes.
