ICE Princess25 [194]

Answer:

E. Weather radio collars are the only practical means that park rangers have for tracking the movement of the rhinoceros in the park.

Explanation:

E. Weather radio collars are the only practical means that park rangers have for tracking the movement of the rhinoceros in the park.

Nowadays there is a lot of technology available for tracking and monitoring of wildlife in big areas. If these radio collars are falling off very frequently and the tranquilizer is being used a lot, it means the method they are using is not the best or very efficient for this type of big animals.

They can use for example GPS trackers in a microchip implanted below the rhinoceroses skin or <u>even inside the horn</u>. With this process the park rangers would just need to use the tranquilizer once to immobilize the animal for a little bit, implant the GPS tracker or microchip; <u>this device won't fall or slip off and won't do </u><u>any harm</u><u> to the rhinos either</u>. This procedure will reduce the risk of the collar falling off and the use of the tranquilizer every time it does fall. Additionally, with this trackers, the park rangers, supervisor or vet can access the information <u>24 hours a day, in real-time</u> from a computer or even an electronic device. This new technology even offers an alarm systems by SMS or calls every time an abnormal rhino activity is detected.

The genes for miniature wings (m) and garnet eyes (g) are approximately 8 map units apart on chromosome 1 in Drosophila. Phenoty
Anestetic [448]

The following phenotypic classes reflect offspring that were generated as a result of a crossover event

  • wild type
  • miniature wings
  • garnet eyes

Explanation:

When the miniature wings and garnet eyes links up with the 8 map unit that are present between them. After that the presence of two recombinant classes must complement together and make 8% of total i.e. they contribute 4% each. together the parental classes make up to 92% by contributing 46% one.

This can be understood through a phenotypic ratio calculation, which can be expected from it.

wild type: 4% x 800 = 32

miniature wings: 46% x 800 = 368

garnet eyes: 46% x 800 = 368

miniature wings, garnet eyes: 4% x 800 = 368
