Answer:

Los gemelos fraternos son "dicigóticos", lo que significa que se desarrollaron a partir de dos óvulos diferentes fertilizados por dos espermatozoides diferentes, mientras que los gemelos idénticos son "monocigóticos", es decir, se desarrollaron a partir de un solo óvulo fertilizado que se dividió.

A fox eats a steady diet of rabbits. No matter how many rabbits the fox eats, he will never start to look like a rabbit, though.

Answer:

Because that's just how it works.

Someone can eat a steady diet of steak and potatoes but they don't turn into steak and potatoes.

When we eat, we consume the meat and energy of the animal. We don't consume some mystical part of them that gives us their qualities.

For example:

You can eat deer meat and not get as quick as a deer, or lion meat and not get the courage of a lion.

We can apply this to the "You are what you eat" phrase people like to use.

Just because you eat a lot of donuts, for example, doesn't mean you'll turn into a donut, or get any donut like qualities (Except maybe stickiness).

1. Populations can have variety, despite being made up of the same species. If a population has different expressed traits, this

fgiga [73]

Natural Selection proposes that organisms that are better adapted to their environment are able to survive and reproduce.

Even though these frogs are the same species, their shades of green is what helps them to survive in their habitat. In this case, frogs with a lighter shade of green are able to be seen by predators easier, whereas frogs with darker shades are able to blend in (camouflage) more with their surroundings. After a period of time, due to them being easily seen, lighter-shaded green frogs will die off.

To anseer your question, natural selection would have a gradual affect on the frequency of the alleles. Lighter-green allele frequencies would eventually cut off, and darker-green allele frequencies will increase.

Hopefully the following image will help:
As seen in the image, (please forgive the quality, as I had drawn this on some random kids drawing site on the internet...) you can see the affects of natural selection on the allele frequencies. The brighter-green shades gradually decrease over time, as the darker shades increase.

Hope you find this helpful.
