Answer:

Inbreeding leaves animals susceptible to genetic disease, and populations to reduced fitness. This family of three would not be able to sustain a population given their a) group dynamics and b) genetic variation

That means less members of the population carry two different alleles of a gene for any given trait. This increases the chance of the appearance of recessive traits, which could be disease causing or otherwise reduce fitness.

With only three related individuals left, the chances of generating a new and thriving population with the limited genetic material is almost non existent, especially considering the animals are a male, female and their pup

Is wavelength directionally OR inversely proportional to frequency?
Luba_88 [7]

Answer:

The wavelength of any wave with a constant speed is inversely proportional to its frequency, because as something vibrates more frequently, there is less time between one vibration and the next. Each complete vibration is one wavelength, so if there is less time, it can only go a shorter distance.
