What mammal has the most chromosomes
rodent Ichthyomys pittieriAbstract. The mitotic and meiotic chromosomes of the semiaquatic rodent Ichthyomys pittieri (Rodentia, Cricetinae) from Venezuela were analyzed by means of conventional staining and several banding techniques. The diploid chromosome number of this rare species is 2n = 92, which is the highest value known for mammals.
How many chromosomes does a banana have
33 chromosomesBanana varieties that are hybrids with AAB and ABB genome constitutions are a staple food for a billion people in Asia and Africa and have 2n=3x=33 chromosomes (Figure 1). About 15% of the world’s banana production is for the export trade, and is based on a single variety, ‘Cavendish’.

Can a dog impregnate a cat
And they do exist—mules, for instance, are the result of a horse and donkey mating. But creating hybrids of animals that are very genetically distinct from each other – such as a dog and a cat – are impossible, as is one species giving birth to an entirely different one. It does not stop people from hoping.
How much DNA do humans share with potatoes
So, it is possible for us to have 80% of the genes found in potatoes while the other 20% being specific to humans or just primates for that matter though that 80% of genes that are similar may have a percent identity (How much a gene sequence is shared between genes of two species) of 40% making the total amount of …

What happens if a human and an animal mate
What happens if a human and an animal mate? Humans are animals too. So if a human mates with another human they are in fact mating with an animal. … Further, the sperm of the animal wouldn’t be able to bind and fertilise that egg of the human and vice versa, so not offspring would come out of this mating.
