Some moth species have a very short window of time for matingeach year. One year the moths were breeding during a week when itwas breezy and their reproductive success was very low. What is thelikely cause of this low success rate?
|
Male moths could not follow the pheromone trails of the femalesbecause the wind dispersed the chemicals |
||
|
Female moths could not produce pheromones due to low wateravailability |
||
|
Female moths did not produce many eggs due to lower wateravailability |
||
|
Male moths grew at a slower rate and were not ready to mate whenfemales were |
Why might workers within a population of haplodiploid eusocialinsects have evolved the “willingness” to help the queen raise moreoffspring (i.e., sisters of the workers) rather than reproducingthemselves? Assume the same male is fertilizing the queen.
|
Workers are more closely related to sisters than they would beto their own daughters, and hence raise their inclusive fitness byhelping raise the queen’s offspring |
||
|
Workers are incapable of reproduction and therefore are makingthe best of a bad situation by helping raise their sisters |
||
|
The workers help to raise the queen’s offspring because there isa good chance that she will return the favor when they becomequeens |
||
|
Workers are genetically identical to each other and thereforework to pass on their collective gene pool |
Answer:
1. The moths couldnt get a high reproductive success rate as theenvironmental conditions were not favourable and hence the male andfemale species of the moth couldnt mate. The main reason for thisis that the female moth releases the pheromones and the male mothdetects them and fly towards that direction to mate. But due to theheavy breeze, the pheromones smell couldnt get detected easily andhence the low reproductive success. Hence the answer to thisquestion is option: Male moths could notfollow the pheromone trails of the females because the winddispersed the chemicals.
2. Theworkers are sterile and all of them share the same genetic pool asif there genes were identical copies to each other. Due to thissimilarity among the workers passed on from their ancestors, theyhave evolved the willingness to help the queen raise moreoffsprings. Hence the answer to this question is option:Workers are genetically identical to each other andtherefore work to pass on their collective genepool.
If youhave any query kindly comment before giving thumbs up. Thankyou.
