Mark the difference between Meiosis and Mitosis below.
- In mitosis the daughter cells are diploids.
- In meiosis the daughter cells are haploids.
Only second generation is asked so the product is 1 diploid only.
Answer:
Plants can reproduce in two ways:
Vegetative reproduction
Fertilization-based reproduction
Explanation:
A cell can be thought of as a "factory," with different departments each performing specialized tasks.
Answer:
Reproductive barrier ⇒ isolation mechanism ⇒ seasonal or temporal isolation.
Explanation:
Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, and the postzygotic mechanism avoids the zygote to develop and reach the adult stage.
Among the prezygotic mechanisms, we might find behavioral isolation, seasonal or temporal isolation, sexual isolation, gamete incompatibility.
Seasonal or temporal isolation occurs when individuals of different species occupy the same area, have the same reproductive behavior, and their gametes are compatible, but they do not get to mate because their reproductive seasons differ.
In the exposed example, after the speciation process, both bird species living together are not capable of mating because one of the species mates in the spring and the other one breeds in fall.
