Natural selection refers to the procedure where the species better amended to their surrounding appear to survive and generate more offspring. Natural selection refers to one of the mechanisms that make modifications in the frequencies of genes in populations and thus, it is the mechanism of evolutionary change.

However, the phenomenon of genetic drift and natural selection cannot take place unless and until there is a genetic variation, that is unless some individuals are genetically distinct from others.

Ray Of Light [21]

Answer:

50%

Explanation:

Let the allele for red-green color blindness be represented by c.

Normal vision woman whose father is color-blind will be X^CX^c

Color-blind male will be X^cY

X^CX^c   x   X^cY

Progeny: X^CX^c, X^CY, X^cX^c, X^cY (See the attached image)

<em>Out of the 2 male progeny, 1 is affected for color-blindness while the other is not affected. This gives a 50% probability that a son of the couple will be color-blind.</em>

For biology i have to pretend im a scientist in the year 3020 and i have to create an animal and explain what the worlds climate
lyudmila [28]

Try mixing two or more animals together to create an animal. Research their physical features, the environment they do well in, senses, etc.

For example:

A cat-like creature with an alligator's tail and a bird's beak.

This creature would have cat-like instincts, but be able to swim underwater to to it's alligator tail (alligators are born to swim) and sing like a bird due to it's beak. Plus you could add anything else you want.

Another thing you could do is look up fantasy animals from video games and get inspired from them!

For worlds, you probably want to build a world that your animal could survive in.

No Man's Sky, a video-game, has endless biomes and worlds that you can take inspiration from for the climate and it's features.

You could also research about any known planets (doesn't have to be in our solar system) and mix two or more together, take aspects from one planet and give it to another, etc!

I hope these ideas helped you a bit :)

If all life is related why are the relationships not always obvious in terms of resemblances, or how much organisms resemble eac
max2010maxim [7]
All life has a common ancestor which can be traced through different lineages. Due to the fact that any new generation comes from two parents who do not share the same features. As the number of generations increases the resemblance to previous ancestors begins to minimize. For example I have brown eyes just like my mother, however, my great great grandmother had hazel eyes.
