can an animal such as a dog or a horse get a girl pregnent why or why not?

Answer 1

A dog can get a girl dog pregnant, but not a girl human. Same with horse.
Reproduction is carried out when one strand of DNA (in the sperm) from the male joins with one strand of DNA (in the ovum) from the female, to form the double helix that is the beginning of a new individual. The chromosomes on the strands match up evenly. The strands of DNA for different species have greatly different numbers of chromosomes and they can't match up to make sense. Only if the 2 species have very similar DNA, as with horse and donkey, can a hybrid be produced; but even then, the DNA doesn't match up well enough that the offspring can reproduce.

Answer 2

The above answers are correct about non-compatible chromosome numbers. Also the definition is true that a species by definition is one that can reproduce with another member of the same species and produce fertile offspring. Some similar species (those who are recently derived) can produce but the result is infertile offspring. For example a Donkey and a Horse are very similar and can reproduce and have a baby Mule. However, two mules cannot reproduce to make baby mules. They are sterile. Two species of salmon can hybridize too with similar results. Animals such as wolves, dogs, dingos, and coyotes can reproduce and have fertile offspring there fore they are all considered same species. It gets difficult when working with insects because they can hybridize more readily and can subspecies exist. Furthermore, the idea of a distant mammals reproducing such as a dog and a human woman would not develop past the stage of insemination. If the sperm could survive in the different species reproductive tract (the body would treat foreign sperm as a foreign object and the immune system would try to defend itself) the sperm acrosome (tip of the sperm cell that opens the egg) could not dissolve the egg cell membrane to inject the genetic information. So the nuclei could never join in the first place. Although it would be fun to make half humans half cats and stuff. I believe in theory it is possible for humans and chimpanzee to hybridize but to do so would be so against the scientific ethics code held by most decent human beings and no one sane person would violate the laws of nature as so.

Answer 3

The answer is NO. The only way for a girl to get pregnant is for someone of her own species (human) to mate with her. The human egg cannot be fertilized by a sperm from any other animal because it is a haploid cell (half a human cell) containing a certain number of chromosomes (all human) which must be met by that same number of chromosomes (all human) to become a complete human cell. Without the egg becoming a complete cell it can never complete the process of meiosis and split into two cells; it cannot reproduce itself. Onle certain animals very close in chromosomal structure can combine to form different species as in the example of horse and donkey.

Answer 4

A dog or horse would not copulate with a human being. firstly.

Secondly, its not biologically possible.

Only species that are genetically very close can produce offspring (like a dog and a wolf, or a zebra and a donkey but not zebra/horse) but that is typically only when forced to do so by humans.

Answer 5

No. they are different species. That is the basic definition of species: different species cannot produce offspring.

(Sometimes closely related species can produce non-fertile offspring, but dogs and horse are not that closely related to humans)

Answer 6

It's not possible as the genetic make up of other animals i.e. chromosomes and genes are different, they can't combine with human genetic material

Answer 7

No, incompatible DNA.

Answer 8

cross species breeding is not possible or recommended.

dude ,ewwww. thats nasty !!!!

Answer 9

no it cant because they don't have enough chromosomes

Answer 10

why would you want to know this? that's sick
