The question is incomplete as it does not have the option which are:
Favorable genes from parental generations provide advantageous characteristics to the hybrid species.
Hybridization produces offspring traits that allow different species to survive in extreme environments.
Inherited traits passed on from parental generations make hybrid species more susceptible to disease.
Hybrid species display more adaptation due to their reduced genetic diversity
Answer:
Favorable genes from parental generations provide advantageous characteristics to the hybrid species.
Explanation:
The white cattail is the plants which grow in the wetlands that are they are adapted to grow in the wetlands. The white cattail species in nature is the result of natural hybridization that is mixing of the genes of two different species of the same genus.
The white cattail can when grown in the Midwestern states well adapted to grow in that area and the reason for this could be accounted that the genes from the parental plants provided many advantages to the newly formed hybrid species.
The teacher most likely asked for additional trials because it was necessary to see data from more plants before the conclusion could be accepted.
Explanation:
Any experiment should have multiple trials given so that accuracy of the result could be obtained.
Repeating same experiments tests the consistency of a particular result and makes sure that the results will not be effected by random events occurring within the system or surrounding.
Thus the conclusion becomes more precise and accurate.
