Answer:
Selective breeding combines ideal traits of animals to replicate in offspring
Explanation:
Selective breeding is the process which involves choosing parents with particular characteristics to breed together and produce offspring with more desirable characteristics. It is also known as artificial breeding and provides both plants and animals with greater variation and higher chances of survival. Selective breeding can be used to produce plants with bigger and tastier fruits and vegetables, crops with greater resistance to pests and diseases, and bigger animals that can be used for meat or milk production. The process of selective breeding is of great importance to the farmer today as it has brought about greater economic advantages.
In the instance of the black-breed boar and the white-breed sow being matched for mating, the reason is to combine these desirable traits in their offspring. The black-breed boar produces quality meat while the white-breed sow has quality fertility. Mating between these two breeds will produce offspring which has both traits of quality meat production as well as quality fertility.
Answer:
The places where the species can thrive principally because of its characteristics is known as the fundamental niche, on the other hand, the place where the species is living is known as the realized niche. In the intertidal region, the species Balanus and Chthamalus compete for space. In comparison, Balanus is a bigger barnacle that can colonize the place more effectively than Chthamalus.
This competition for space makes Chthamalus displace into higher regions where water is not the same as in lower levels. The fundamental niche of Chthamalus comprises both lower and higher levels, while the realized niche for Chthamalus is the higher levels. In case, if the competition with Balanus was non-existent, the Chthamalus would occupy the lower levels.
