What does it mean when observed genotype frequency is different from expected genotype frequency in Hardy-Weinberg equilibrium?
As I understand it, if a population is at Hardy-Weinberg equilibrium, then the genotype frequencies should be $$p^2 + 2pq + q^2 = 1,$$ given the allele frequencies of $p$ and $q$, which you can figure ...

How do we know that the DNA we share with other species (especially primates) isn't fully the result of transposable elements?
I recently read a couple studies that concluded the 25% of genetic similarity between cows and reptiles is actually primarily due to TEs (transposable elements) rather than common ancestry.
Here's the ...

How does the total number of genes increase throughout the course of evolution?
Campbell Biology says:
A typical prokaryotic cell has about 3,000 genes in its DNA, while a
human cell has about 21,300 genes.
If evolution depends on random mutations occurring in the genome, ...
