Reproductive Isolation I Practice, Apply Your Knowledge

Horse+ Donkey= Mule (sterile) what type of reproductive isolation?

Hybrid sterility→ two species can mate, and offspring are viable but sterile.

What type of reprodtive isolation is this?

Temporal isolation→ breeding seasons or years (can be time of day) differs between two geographically overlapping species.

Nectar seekers of other species don’t come into contact with the pollen. What type of reproductive isolation is this?

Mechanical isolation→ morphological differences in the mechanics of reproduction keep the gametes apart.

Similar geographic area, different habitats. What type of reproductive isolation is this?

Habitat isolation→ the species inhabit the same geographic area, but the habitat differs, keeping the organisms separate.

What type of reproductive isolation is this?

Behavioral isolation→ Differences in behavior (usually a courting behavior) prevents two species from mating

What type of reproductive isolation is this?

Hybrid inviability→ hybrid zygotes are created, but don’t survive through development due to interactions between genes of parents

What type of reproductive isolation is this?

Gametic isolation→ gametes are incompatible; the sperm of one species not able to fertilize the eggs of another species.
