Hey future biologists, ready to dive into the mind-blowing world of epigenetics? Get comfy, because we&#39;re diving deep! 🏊&zwj;♀️

<ul>
	<li>Epigenetic Tags and Their Removal</li>
	<li>Genomic Imprinting</li>
	<li>Mendelian vs. Non-Mendelian Inheritance</li>
	<li>Real-world Examples</li>
</ul>

<ul>
	<li>What are they?
	<ul>
		<li>Epigenetic tags are like little notes (Post-its, if you will) on your genes that tell your cells how to read them. These tags don&#39;t change the DNA sequence, but they do influence how genes behave.</li>
	</ul>
	</li>
	<li>What happens during baby-making? 🍼
	<ul>
		<li>Around 99% of these tags get wiped clean in sperm and eggs. It&#39;s like your cells do a factory reset before passing genes to the next generation.</li>
	</ul>
	</li>
</ul>

<ul>
	<li>What is Genomic Imprinting?
	<ul>
		<li>This is when the gene from one parent is silenced (think of it like putting tape over a parent&#39;s mouth 🤐). Meanwhile, the gene from the other parent gets the limelight.</li>
	</ul>
	</li>
	<li>Why is it special?
	<ul>
		<li>Normally, you get two copies of each gene, one from mom and one from dad. But in genomic imprinting, it&#39;s like you&#39;re acting with only one gene! Imagine having two cookies 🍪 but only being allowed to eat one.</li>
	</ul>
	</li>
</ul>

<ul>
	<li>Mendelian Inheritance
	<ul>
		<li>In this typical inheritance, if you get one broken gene (recessive) and one working gene (dominant), you&#39;re all good! The dominant gene got your back! 🦸&zwj;♂️</li>
	</ul>
	</li>
	<li>Genomic Imprinting
	<ul>
		<li>It messes up the game. The dominant gene can get silenced, and suddenly that recessive gene you didn&#39;t worry about is causing all sorts of drama. 🎭</li>
	</ul>
	</li>
</ul>

<h4>Case 1: Angelman Syndrome 👼</h4>

<ul>
	<li>Imagine a mom with a recessive gene for Angelman syndrome and a dad with a dominant healthy gene. Normally, you&#39;d expect the baby to be fine. BUT if the dad&#39;s gene gets silenced, guess what? The baby will have Angelman syndrome!</li>
</ul>

<h4>Case 2: Lion 🦁 vs. Tiger 🐯</h4>

<ul>
	<li>Female lions might have cubs from multiple dads! (Talk about a blended family, eh?)</li>
	<li>Daddy lion wants big cubs, mommy lion wants many cubs. Their imprinted genes usually balance out.</li>
	<li>But pair a lion with a tiger and suddenly, the balance is like a seesaw with a hippo on one end! Why? Because tigers don&#39;t have multiple dads for the cubs, so the imprinted genes don&#39;t get that &quot;natural balancing.&quot;</li>
</ul>

So there you have it, folks! The wonderful world of epigenetics and genomic imprinting. These tags and imprints are like the behind-the-scenes crew in a movie, making sure everything runs but never getting the glory. 🎬
