why is it said that natural selection acts on phenotypes rather than on the genetic material of an organism?

Biology

Phantasy [73]3 years ago

It is said because it doesn't change the genetic material, but the outside of the animal when the species slowly adapts to it's surroundings and predators.

Example: A group of 10 birds are in a forest. One of the birds has a short, stubby beak, and another 3 have long, thin ones. The rest of them are normal. If the only food left after a natural disaster was flower nectar, then the 3 with the long, thin beaks would survive, and the other birds, poorly adapted for this outcome, would not live.

It doesn't actually change the genetic makeup of an organism but may slowly alter it's entire gene pool over time.

Taxonomy

The Radio-ulna and digits of most primates and animals represents a homologous structure




An example of another internal structure is the genes.
The homologous chromosomes have the same genes in common. Each cell has at least two sets of chromosomes which one comes from one’s father also called as paternal chromosome and mother, called as the maternal chromosomes. These chromosomes are what makes the child obtain the characters and may depend on the traits the parents possess. Homologous chromosomes are not duplicated chromosomes or identical however, they are analogous or similar. The alleles for a specific characteristics isn’t the same but the same genes are in the same order.<span> </span>

What causes ocean water to become denser?
Solnce55 [7]
There are two things that cause ocean water to become denser, and those are b) the salinity of water and low temperatures.
The more salt there is, the denser the water will be - take the lake Dead Sea in Israel, Jordan, and Palestine for example.
And the lower the temperature, again, the denser the water will be - the deeper you go into an ocean, it will be more difficult to move around due to density and other things.
