<span>"Since the discovery of Galapagos in 1535, humans have brought many alien species to the islands—some intentionally, including goats, pigs, cats, and both ornamental and food plants (vegetables and fruits), to name a few—while others, including rodents, insects, and weedy plants, have been carried to the islands accidentally." </span>
The purpose for which a pedigree chart might be prepared is to identify the pattern of inheritance of a particular trait.
This pedigree chart is created so as to see which traits this new offspring has inherited from its ancestors and which may possibly be transferred onto a new offspring later on in its life. It is formed in order to find patterns of inheritance and see what the most important traits that get inherited are.
Answer:
D - Its genetic diversity is very low
Explanation:
An extinction vortex can be defined as the process which populations in decline pass through to drive them into a vortex of smaller populations, endangering their survival as they tread the path to extinction.
Populations that fall to extinction vortex already have small populations which is usually as a result of certain powerful genetic factors, which cause the populations to continue to decline in size.
During genetic drift which occurs in all populations, small populations tend to lose genetic diversity as a result of the random nature of gamete sampling.
This is because any change in alleles in a small populations can have dastardly effects on the populations size due to a small gene pool.
