Introduction to Meiosis and Gamete Formation
This video provides an explanation of meiosis. It covers the concept of haploid and diploid cells, chromosomes, and how gametes are produced through meiosis. The video also explains how fertilization restores the full number of...

Hormones and Sexual Behavior
We've already learned about hormones in the context of the endocrine system, but now let's get a closer look at how these influence the development of sexual characteristics as well as sexual behavior. How and when does this happen? How...

Coupling of Folliculogenesis & Oogenesis
In this video, we see how various stages of oogenesis correlate side-by-side with folliculogenesis.

Gene Linkage and Genetic Maps
We just learned about X-linked genes, but what about gene linkage in general? If two genes are on the same chromosome, we can say that they are linked. Are they always inherited together? Can the alleles rearrange in some way? Well don't...

Types of Reproduction
In this live-action program viewers will learn from a biological standpoint, the only point of reproduction is to transmit DNA from one generation to the next. Students will come to understand that organisms reproduce in two ways:...

Sexual Reproduction in Flowering Plants: The Development of the Ovum (Egg)
Plant Reproduction Set: 4. This clip explains the complex process by which an ovum is produced in the ovule of a flower.

Alteration of Chromosome Number and Structure
We've already learned about certain kinds of modification to the genome, namely in the way of mutations that can occur to specific base pairs, or frameshift mutations when base pairs are deleted or inserted. But there can also be...

Meiosis, Gametes, and the Human Life Cycle
We know that your body produces more cells through mitosis. But where did your very first cell come from? It can't have been mitosis, because mitosis needs a cell to start with. As it turns out, meiosis and subsequent fertilization are...

BIOLOGY - Genetics - Mitosis
Mitosis produces identical copies of cells, and is involved in growth, cell repair and asexual reproduction - which is how simple organisms reproduce. When cells divide by mitosis, two new cells form and each cell is identical to one...

Understanding Meiosis: The Key to Genetic Diversity
This video explains the process of meiosis, which is essential for sexual reproduction. It details how cells undergo two rounds of division to produce four genetically diverse sex cells with only half the number of chromosomes. Through...

Reproductive System
Begin looking at reproduction by contrasting sexual reproduction with asexual reproduction. Sexual reproduction gives us genetic variation as meiosis creates brand new chromosomes through cross over. Male and female anatomy is covered,...
