Answer:
The most appropriate answer would be D. The western skink population would be separated into two groups, and genetic diversity would decline in each group.
It can be explained with the help of a bottleneck effect due to which population size decreases suddenly due to events like a natural disaster, habitat destruction et cetera.
The construction of the multi-lane highway would have destroyed the natural habitat of western skinks and separate them into two populations.
The separation of a population along with the destruction of habitat would result in a severe decrease in the population size of western skinks.
Consequently, the genetic diversity would also decrease.
Answer:
Polygenic inheritance
Explanation:
In polygenic inheritance, one characteristic or trait is controlled by a combination of two or more than two genes. As several genes control a trait in a polygenic trait therefore there are many possible phenotype is possible in this situation.
In humans, examples of polygenic traits are eye color, hair color, skin color, height, body shape, body weight, etc. There is equal influence of gene which are contributing to a trait in polygenic inheritance. So complete dominance is not seen in polygenic traits. Therefore the correct answer is polygenic inheritance.
They are called Zircons, they date back to almost 4.4 billion years ago. Hope this helps, please give me the brainiest, thanks.
