Which Example Describes Hybrid Inviability?

The mechanism of hybrid inviability occurs when an egg of one species is fertilized by a sperm from another species, but the fertilized egg cannot develop past the early embryonic stages. Hybrid Sterility: an interspecies hybrid maybe viable but sterile. example would be a mule.

What is hybrid Inviability in biology?

Hybrid inviability is a post-zygotic barrier, which reduces a hybrid's capacity to mature into a healthy, fit adult. The relatively low health of these hybrids relative to pure-breed individuals prevents gene flow between species.

Which is an example of hybrid sterility?

An example of an intraspecific hybrid is a hybrid between a Bengal tiger and an Amur (Siberian) tiger. ... The offspring of an interspecific cross very often are sterile, this hybrid sterility prevents the movement of genes from one species to the other, keeping both species distinct.
