Two species that occasionally mate and produce zygotes, but that have incompatible genes that prevent the resulting embryo from developing, are affected by
A)gametic isolation.
B)reduced hybrid fertility.
C)reduced hybrid viability.
D)hybrid breakdown.

Question

Quizplus · Accepted Answer

The phenomenon where two species occasionally mate and produce zygotes that are not viable due to incompatible genes is known as reduced hybrid viability. This means that the offspring may not be able to develop properly and may die before reaching maturity. Gametic isolation is the prevention of fusion of gametes from different species, reduced hybrid fertility refers to the inability of hybrids to produce viable offspring, and hybrid breakdown refers to the decreased fitness of the offspring of hybrids over generations.
