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,...

A presentation which concentrates on the development of the blastocyst and embryo after fertilization. Topics begin with the scientific names and processes at each stage and then develop into an explanation of embryonic and somatic stem...

An overview of the early development of a zygote to an embryo. Understand embryonic and somatic stem cells. [19:55]

An overview of early development of a zygote to an embryo. Embryonic and somatic stem cells. [19:55]

An overview of sexual reproduction and how mitosis and meiosis occur to form a particular species. [18:23]

The explanation of how a fertilized egg develops once it has become a zygote. [19:54]

Walk you through the stages of pregnancy, beginning with how a zygote forms to the hormonal signals that lead to labor. [10:45]

Overview of fertilization and early human development, from conception leading to a zygote to blastocyst, embryo and fetus. [7:59]

In this video [9:34] learn how a zygote, the single cell produced by fertilization, divides by mitosis to produce all the tissues of the human body (including germ cells, which can undergo meiosis to make sperm and eggs).

This lesson will explain how a zygote develops into an embryo. It is 2 of 5 in the series titled "Zygote."
