What are the 2 types of reproductive barriers?
Reproductive barriers are mechanisms that prevent species from mating or producing viable offspring, and they are classified into two main types: prezygotic and postzygotic barriers. Prezygotic barriers occur before fertilization and include factors like temporal isolation, habitat isolation, and behavioral isolation. Postzygotic barriers happen after fertilization and involve issues such as hybrid inviability, hybrid sterility, and hybrid breakdown, which affect the viability or fertility of the offspring. These barriers contribute to the process of speciation by maintaining distinct species.
Is the gallbladder chemical or mechanical breakdown?
Since there is no machinery in the body, it is a chemical breakdown.
What Glycerol is produced from the breakdown?
Glycerol is produced from the breakdown of lipids which are fats or oils
What waste chemical comes from the breakdown of proteins?
Breakdown of proteins produce aminoacids.
How does mechanical breakdown helps chemical breakdown?
Mechanical breakdown helps chemical breakdown because when you chew, chemical breakdown is going on all at the same time. So, that is going to chemical because if you didn't have saliva (chemical breakdown) if would take real long to digest your food.
Can a biological species produce infertile offspring?
Yes donkeys are not fertile due to hybrid breakdown.
What is an example of hybrid breakdown?
Hybrid breakdown is a form of postzygotic reproductive isolation that occurs when hybrid offspring between two species are viable and fertile in the first generation but produce inviable or sterile offspring in subsequent generations. An example of this can be seen in certain species of frogs, such as the Rana species, where hybrids between two closely related species may survive but exhibit reduced fitness and fertility in their offspring, ultimately leading to a decline in hybrid population viability over generations.
What is the postzygotic reproductive barrier?
A postzygotic reproductive barrier refers to mechanisms that prevent successful reproduction after fertilization has occurred. These barriers can lead to hybrid inviability, where the hybrid offspring do not develop properly or survive to adulthood, or hybrid sterility, where the offspring are unable to reproduce (e.g., mules, which are hybrids of horses and donkeys). Other outcomes include hybrid breakdown, where the first generation of hybrids is viable and fertile, but subsequent generations are weak or sterile. Overall, postzygotic barriers contribute to reproductive isolation between species.
