It is most common when two organisms of different species attempt to reproduce. The combination of genes is usually not fully functional meaning that the offspring is unable to reproduce itself.
This can also occur in plants although to a lesser extent as plants are capable of polyploidy. In humans polyploidy causes complicated genetic diseases.
A mule is an infertile hybrid of a donkey and a horse.
It means that a hybrid species will not be able to conceive a child as it is infertile. In other words, if a hybrid is produced between two species of animals, it will not be able to reproduce.
Yes donkeys are not fertile due to hybrid breakdown.
Hybrid offspring can come from species with differing numbers of chromossomes, making them infertile.
Ligers are infertile because since tigers and lions are different species, they can mate with each other but produce infertile offspring due to mutations that occured as the two species evolved apart from one another. Similarly, horses and donkeys can mate to produce mules, but the mules are infertile.
Breeding of different species of snakes is rare and the hybrid is usually infertile. A recent television show mentioned a super hybrid of pythons and cobras, but that has not and is unlikely to happen.
By breeding a horse and a donkey together, the offspring will be infertile due to the different chromosome pairs of the parents. Mules are known as a hybrid, they have 63 chromosome pairs that enable them to unsuccessfully reproduce.
Different species of birds do not usually interbreed. When they do the resultant hybrid birds are probably infertile. [It only happpens with closely related birds, occasionally seen with ducks.]
No. If a woman is infertile, sperm will have no effect on her. Infertile means she cannot get pregnant.
Infertile also means unproductive or barren.
Yes, I'm afraid so, anyone can be infertile.
Fertile will support plant life, infertile will struggle.
