<p>Hello viewers!<br>My name is <strong>Adebanke</strong>, and welcome to today’s class on <strong>Genetics and Heredity</strong>. In this lesson, we will explore fundamental concepts such as <strong>DNA structure, Mendelian inheritance, genes, chromosomes, and genetic disorders</strong>. These topics are core areas in biology and frequently appear in exams like <strong>WAEC, NECO, JAMB, and international assessments</strong>.</p>

<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>When you think of genetics, you probably think of <strong>DNA</strong> and specific traits that appear in families. Some families have members who are mostly tall, while others might have shorter members. Genetics is the study of <strong>how traits are inherited</strong> from one generation to the next.</p>

<h2 class="wp-block-heading" id="h-what-is-heredity">What is Heredity?</h2>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>Heredity refers to the <strong>passing of traits from parents to offspring</strong> through genetic material (DNA). For example, if a parent has full hair, that trait can also appear in their children. These inherited traits explain similarities between family members.</p>

<h3 class="wp-block-heading" id="h-structure-of-dna">Structure of DNA</h3>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>DNA has a unique structure often compared to a <strong>twisted ladder</strong> (double helix). The long strands form the sides of the ladder, while paired bases form the rungs. These base pairs include:</p>

<ul class="wp-block-list"><!-- wp:list-item -->
<li>Adenine (A) with Thymine (T)</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li>Cytosine (C) with Guanine (G)</li>
<!-- /wp:list-item --></ul>
<!-- /wp:list -->
<!-- wp:paragraph -->
<p>The structure is made up of <strong>nucleotides</strong>, which are the building blocks of DNA.</p>
