Recommend an action humans could take to help prevent the extinction of tropical organisms
Art [367]

Answer:

Stop habitat destruction

Explanation:

Cutting down and burning forests basically take away the shelter, hunting grounds, and overall habitat away from many species that use the trees as a form of shelter and protection. Removing their shelter, which could be their only form of protection causes many of these organisms to die, not to mention the plants that are necessary to keep the food chain balanced.

The genes for miniature wings (m) and garnet eyes (g) are approximately 8 map units apart on chromosome 1 in Drosophila. Phenoty
Luden [163]
<h2>Answer is option " 2 & 4"</h2>

Explanation:

  • Two types of posterity can be created subsequent to mating: parental and recombinant. Recombinants are created because of the traverse of non-sister chromatids at the hour of gamete arrangement. Here, mating happens between m+g/mg+ female and mg/mg male so the posterity would be separated as follows:  
  • m+g/mg : Parental  
  • mg+/mg : Parental  
  • m+g+/mg : Recombinant  
  • mg/mg : Recombinant  
  • m+g+/mg (wild sort) and mg/mg (smaller than usual wings, garnet eyes) are the recombinants thus they were created because of the hybrid occasion.
  • Hence,the right answer is option 2 & 4 "wild type and miniature wings,garnet eyes"
