Yes two different species can have same chromosome number or can also have different chromosome number. Same goes for genus or family, they can have same or different chromosome number.
What organisms have the same number of chromosomes?
Broccoli, cabbage, kale, kohlrabi, brussels sprouts, and cauliflower are all the same species and have the same chromosome number.
Why might two organisms have the same number of chromosomes but not the same traits?
Chromosomes are paired because an individual receives one set from each parent. For example, chromosome pair number 15 codes for the same genes, but each chromosome might have different alleles, or variations of the same gene.
Are there any animals that have the same amount of chromosomes as humans?
Potatoes and Chimpanzees, for example, both have 24 pairs of chromosomes. Humans are not the only animal with 23 pairs, either–the Chinese subspecies of Muntiacusmuntjac, a small kind of deer, also has 23 pairs of chromosomes.
Can animals with the same number of chromosomes mate?
Some species have chromosomal polymorphism and can mate even with different numbers of chromosomes. The southern short-tailed shrew (Blarina carolinensis) has diploid numbers of 35, 36, 37, 38, 39, 40 and 41 and fundamental numbers of 41, 42, 43, 44 and 45. They can all interbreed.
Why do animals have an even number of chromosomes?
The reason why the majority of organisms have an even number of chromosomes is because chromosomes are in pairs. … Another exception would be polyploidy , which occurs when organisms have more pairs of chromosomes than a diploid cell does. Below is a picture to help visualize polyploidy.
What happens when you have 47 chromosomes?
Humans have 23 pairs of chromosomes. A trisomy is a chromosomal condition characterised by an additional chromosome. A person with a trisomy has 47 chromosomes instead of 46. Down syndrome, Edward syndrome and Patau syndrome are the most common forms of trisomy.
Why some species have the same chromosome number but they are different?
Originally Answered: Why does the number of chromosomes vary between species? There exist some relation between the complexity of an organism and the number of genes in its genome. For example, some simple bacteria have only 500 genes, compared to about 25,000 for humans.
Why and how do organisms vary in their chromosome number?
Chromosome numbers vary significantly in different organisms. … Especially in those organisms with more chromosomes, the ability of homologs to find one another, pair, and remain together during the first meiotic division is critical to avoid chromosome mis-segregation and resulting aneuploidy.
Do all organisms have 46 chromosomes?
All organisms do not have the same number of chromosomes. For example, human cells have 46 chromosomes, each whereas dogs have 39 chromosomes in each…
Do all mammals have the same number of chromosomes?
These species may have the same number of chromosomes, but the arrangement of chromosomal arms and of DNA across the chromosomes is undoubtedly different among almost all of them. Within mammals, chromosome number doesn’t usefully correlate with complexity or intelligence or whatever.
Do larger animals have more chromosomes?
there is no relationship between size of organism and its chromosome number. A smaller organism may have more chromosomes than a larger organism.
Can a human impregnate a pig?
For the first time, researchers have successfully grown human cells inside early-stage pig embryos in the lab, creating pig-human hybrids, which the researchers describe as interspecies chimeras. … This is a proof-of-concept experiment showing that human-pig hybrids are possible.
Can a lion and a tiger mate?
Although lions and tigers may mate in the wild, they are separated by geography and behaviour, and thus all known ligers stem from accidental mating between lions and tigers as well as from directed breeding efforts that have occurred while in captivity.
Can a dog and cat mate?
The most straightforward answer to this would be: No, a dog cannot successfully mate with a cat and create an offspring. However, the aforementioned video clips show a dog mounting a cat and, rarely, vice versa.
