Question

A major part of an ecosystem was washed away by a flood. Only two male deer and two female deer survived from the original population of 50 deer. The four deer mate and produce offspring. Over time, the population of deer grows. Which prediction is most likely for the future generations of deer? A. They’ll have higher genetic variation than the original population. B. They have a higher risk of mating with a related mate. C. The offspring will be genetic clones of each other. D. Individual offspring will be unable to develop random genetic mutations.

Answer 1

b

Step-by-step explanation:

Answer 2

The correct answer is: B. They have a higher risk of mating with a related mate

The effect that happened to the deer is called bottleneck effect. Bottleneck occurs when a population's size is reduced due to environmental events such as earthquakes, floods, fires, diseases..The genetic variation in that population is decreased and the same genes are passed in the next generation. As the result, the chances of inbreeding and genetic homogeneity can increase.

Genetic diversity might increase when genes flow from another population.
