Genetics | Dihybrid Crosses (Example 1)

This exciting program takes a glimpse at some of the amazing advances in modern genetics. Starting with the discovery of DNA, students will be exposed to advances such as the creation of recombinant DNA, vaccines, the human genome...

Histology of the testis.

It explains the process of fertilisation and describes how the zygote gets implanted in the uterus after fertilisation.

In this video, young people learn the basis of human reproduction in adults, starting with the journey of the sperm to leave to the male reproductive system, and the egg to move from the ovary to the uterus. We'll learn that it takes two...

This video explains how sex is determined in humans and animals, focusing on the role of chromosomes in determining gender. It explores the genetic basis of sex determination, highlighting the contribution of the father's sperm in...

Most babies are conceived by a sperm fertilising an egg, and the foetus growing inside the mother’s uterus. But sometimes this is not possible; one or both parents might have fertility problems For lots of different reasons, some parents...

Biological Classification Set: This clip presents the three basic divisions of the plant kingdom: Bryophyta, Tracheophyta, and Spermatophyta.

In this video, young people learn the basis of human reproduction in adults, including sexual intercourse and fertilisation of the egg. We learn that it takes two parts to make baby, and that anatomical words related to reproduction are...

This video explains infertility and the various treatments available for it. The video discusses two types of treatments - fertility drugs and in-vitro fertilization (IVF). Both treatments have advantages and disadvantages, and the video...

Plant Reproduction Set: 8. This clip explains how plants exist in two alternating forms: diploid sporophyte generation and a haploid gametophyte generation.

The video discusses the topic of infertility and ways to treat and overcome it. It explains how fertility problems can affect both male and female partners and introduces Assisted Reproductive Technology (ART) as a solution. The process...

When we talk about clones in science we mean organisms that are identical copies - they have the same DNA as each other. Identical twins are examples of naturally occurring clones. Both plants and animals can be cloned. Watch this video...

A short video tutorial on the female reproductive system.

In this Nature League Lesson Plan, Brit discusses the different ways that life on Earth makes more life on Earth - sexually and asexually.

Learn more about pollination in plants.

Over 4000 years ago, Ancient Egyptians were far ahead of their time. They had advanced architecture, agriculture, writing and even birth control. Crocodile dung, Acacia fruit, pomegranate seeds and lamb intestines were just a few of the...

This CTE Health Sciences video covers proper use, pronunciation and definitions of medical terminology pertaining to the Male Reproductive System. Rather than opening up a book and trying to learn all the medical terminology out there;...

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...

Learn exactly what these different terms mean, that you will come across in genetics and cell division: Gamete, Chromosome, Gene, Allele, Dominant, Recessive, Homozygous, Heterozygous, Genotype, Phenotype, Haploid & Diploid

This clip demonstrates, step by step, the process of reproduction in mosses.

In this video we learn about the distinct differences of egg and sperm cells, which are also known as gametes. We will see how the chromosomes from each cells come together to form our unique genetic code. The gametes (sperm and egg...

This is a follow-up video to male reproductive anatomy; we cover the components of the ejaculatory pathway and glands that generate semen.

Mendel proposed that you inherit a gene either from your mother, or from your father. But not a mixture of both. In this video we are going to look at monohybrid crosses using Punnett squares. A monohybrid cross is the study of the...
