Hey there future biologists! Get ready to dive into the mind-boggling world of allele frequencies, Darwin, Mendel, and PINK FLOWERS! 🌺

Darwin Says: If you&#39;ve got the traits to survive, you&#39;re gonna make more babies! 🐣

&nbsp;

Real-world Example: Imagine you&#39;re a bird with a beak that&#39;s PERFECT for picking berries. More berries = more food = more baby birds. Your beak trait passes on. Congrats, you&#39;re a winner in the game of life!

Mendel Says: Traits aren&#39;t a blend of Mom and Dad; they come in distinct units called genes!

&nbsp;

Real-world Example: Think of your genes like a deck of cards. You get half from mom and half from dad. You can&#39;t have a half-Queen and half-10 card; each card (or gene) is distinct!

Weismann Says: Your muscles from weightlifting won&#39;t get passed down to your kids. Sorry, Arnold Schwarzenegger!

&nbsp;

Real-world Example: If you dye your hair purple, your future babies won&#39;t be born with purple hair. Traits are inherited through sex cells, not somatic (body) cells.

What Is It?: Darwin&#39;s survival of the fittest + Mendel&#39;s genetics + Weismann&#39;s germ theory = Neo-Darwinism. It explains why we&#39;re all different and how the best traits get passed down.

Plain English: If a certain version of a gene becomes more common, that&#39;s evolution, baby!

&nbsp;

Real-world Example: Say 80% of bunnies 🐰 in a forest are white and 20% are brown. A big freeze comes and the white bunnies are easier for predators to spot. Next year, you might find more brown bunnies around. That&rsquo;s evolution!

<ul>
	<li>Genotype <code>CR CR</code>: Red flowers</li>
	<li>Genotype <code>CW CW</code>: White flowers</li>
	<li>Genotype <code>CR CW</code>: Pink flowers (because the alleles are codominant)</li>
</ul>

Generations Breakdown

<ul>
	<li>1st Gen: 50% red, 50% white</li>
	<li>2nd Gen: 100% pink</li>
	<li>3rd Gen: 50% pink, 25% white, 25% red</li>
</ul>

Allele Frequency: In each generation, 50% <code>CR</code> and 50% <code>CW</code>.

&nbsp;

Real-world Scenario: Imagine if bees 🐝 LOVED white flowers and mostly pollinated them. What would happen? Over time, we might see more white flowers in the population! Now, that&rsquo;s evolution based on preference!

Just to prove the allele frequencies are stable at 50% <code>CR</code> and 50% <code>CW</code>

1st Gen: 50% <code>CR CR</code>, 50% <code>CW CW</code> 
2nd Gen: 100% <code>CR CW</code> (still 50% <code>CR</code> and 50% <code>CW</code> if you break it down) 
3rd Gen: 50% <code>CR CW</code>, 25% <code>CR CR</code>, 25% <code>CW CW</code> (yet again, 50% <code>CR</code> and 50% <code>CW</code>)

&nbsp;

And voila! Even if the colors change, the allele frequencies stay the same. 🌈

&nbsp;

Alright, future scientists, we just covered a TON. Let me know if you have questions, and may your love for biology evolve! 🌟
