Predators are the keystone species because they limit the population of prey.
<h3><u>Explanation:</u></h3>
Predators are those species which hunt for other animals to consume them as food and live. Where prey are those animals who are being hunted and killed by predators.
Keystone species are those species whose absence or removal from a ecosystem will greatly reduce the diversity from the ecosystem to a huge extent.
Now, if a predator like lion is eliminated from the ecosystem, then the prey like deer, goats etc in the ecosystem will live and reproduce at a very high rate, which will greatly increase the population density of these species. So the food for them will be killed at a very high rate, decreasing the plant varieties and population. So the overall diversity in the ecosystem will be highly reduced.
So the predators like lions, tigers, etc are the keystone species of an ecosystem.
Answer:
It is possible to determine their functions and to identify the mechanism involved in their mode of inheritance
Explanation:
Matrilineal inheritance refers to the inheritance of genes directly from the mother, it either through the inheritance of mitochondrial DNA or by the epigenetic mechanism of genomic imprinting (in the case above indicated, maternal imprinting). By mutating genes which are inherited from the mother it is possible to study their functions as well as their mode of inheritance. By using a reverse genetics approach, many maternal imprinted genes have recently been identified to be involved in embryo development, especially in model organisms like <em>Drosophila</em>.
