Suppose that zonosemata flies whose own wings had been clipped and reattached were attacked more frequently than untreated zonos
umka21 [38]

Answer:

All results for the experimental groups involving wing surgery would be invalid.

Explanation:

The experimental group involving wing surgery would not lead to correct results because it is a direct parameter that is impaired. This has been already clearly stated in the question that these flies are prone to attack compared to those which are not treated. There could be several reasons for that such as: (1) the reattachment would not have been successful, and/or (2) the flies' health (fitness) status would have been compromised.

On the other hand, it is not correct that all experimental groups will lead to incorrect results because the untreated flies were not attacked (or less attacked). Similarly, there is no condition given for houseflies rather only zonosemata flies. So 3rd option is also not possible. Finally, the reliability of the results would definitely change because the treated flies would be more attacked and lead to a clear difference in results.

Neurospora is an ideal organism to study the effects of genetic mutations because of several reasons. What is one of these
yawa3891 [41]

Answer:

Due simple growth.

Explanation:

Neurospora is an ideal organism to study the effects of genetic mutations because it is easier to growth and are simple. Neurospora crassa is used as a model organism because it has a haploid life cycle and easier to grow that makes genetic analysis simple. Analysis of genetic recombination is facilitated by the ordered arrangement of the products of meiosis in Neurospora ascospores so due to simple growth and haploid life cycle we can considered   Neurospora is an ideal organism.
