1. Ligers are not a "man-made" creation. They are the result of a male lion and a female tiger that have been raised together and decide they like each other enough to breed.
2. King of the big cats is the liger, a lion father and tiger mother bred together in a way that enhances both species' gene expression for size, resulting in a cat that's about eleven feet tall and nearly a half a ton in weight.
3. But successful interbreeding is the key, and the hybrid offspring are usually sterile and short-lived.
1. Both alleles are present in the offspring
2. Multiple alleles have co-dominance
3. Each make a slightly different protein
4. Each allele changes the outcome
5. Two alleles of a gene which result in distinctly different phenotypes, but when they are both inherited together in an individual the individual has both of the phenotypes.
