Answer:
The F2 generation can be explained because the alleles for flower colour and pollen shape are linked.
Explanation:
<em>When two alleles are linked on the same chromosome, there is a high tendency for the alleles to be inherited together. Consequently, the frequency of the alleles recombining in subsequent generations is low.</em>
This is what Bateson and Punnet observed. There exist a linkage between P and L alleles and also p and l alleles, thereby increasing their frequencies of occurring together and decreasing the frequency of their recombination.
Thus, the F2 generation observed by Bateson and Punnet is due to linkage of alleles.
The correct answer is - b) parasitism.
The kudzu is a plant that has adapted to get stuck to the other plants, usually trees and bigger shrubs, and get nutrients and water through them. In this way, the kudzu shows elements of parasitism, as it is using a host plant in order to satisfy its needs.
The native plants and shrubs will have a big problem with an introduction of the kudzu in their environment. They will not have a defense mechanism, and the kudzu will spread out very quickly and suck the nutrients and water out of them, hindering their growth and even killing them over the coarse of longer period of time.
This would be a prime example of parasitic relationship between the kudzu and the native plants.
Answer:
While protozoans evolved early and have survived to the present day as unicellular organisms, they have undoubtedly undergone considerable evolutionary change. So the role they have is rather big because they where here from early days. Animals could of adopted and learned from them
