Hybrid generally refers to any offspring resulting from the breeding of two genetically distinct individuals, which usually will result in a high degree of heterozygosity, though hybrid and heterozygous are not, strictly speaking, synonymous. a genetic hybrid carries two different alleles of the same gene.. A hybrid, also known as cross breed, is the result of mixing, through sexual reproduction, two animals or plants of different breeds, varieties, species or genera.Mule, a cross of female horse and a male donkey. Hinny, a cross between a female donkey and a male horse. Mule and hinny are examples of reciprocal hybrids.
Chimeras (which in Greek mythology are fire-breathing hybrid creatures) are created by adding human cells to animal embryos, which are then implanted into a host for gestation. To grow human organs, for example, scientists could engineer an embryo so it is missing a specific organ. Labs in the US are growing human-animal hybrids that could one day be used to grow organs for transplants. The idea of human-animal chimeras is not new – in 2003, scientists in China announcing they had successfully fused human cells with rabbit eggs. Crispr- Gene editing technologies, including CRISPR-Cas9, now offer us the ability to directly modify or correct the underlying disease-associated changes in our genome. We now have the ability to change your DNA!
