How is it that humans share 50 of DNA with bananas For the H

How is it that humans share 50% of DNA with bananas?

For the Hardy- Weinberg equation, does it matter if i have different allele frequencies or it only matters if it adds up to 1? I did an experiment testing a f1 and a f3 generation. the allele frequencies differed however the frequencies still added to one (p2 + 2pq + q2=1). do they still meet hardy-Weinberg standards?

thank you

Solution

1).

The theory of descent with modification proposes that all the organisms were evolved from the pre-existing ancestors and the theory of natural selection describes how changes have occurred in some organisms during the evolution process.

The inheritance of gene pool from generation to generation alters to promote the survival adaptations. The mostly used organs undergo more specific changes, while the less used organs become rudiment, this is the basic mechanism behind the evolution.

As all the organisms evolved from the same ancestor, we do share genes with all other organisms including the bacteria. .
