LESSON 5

REPRODUCTION & INHERITANCE

Learning goals 

• I know what parts belong to the human male reproductive system.
• I understand and can explain how these parts work. 

Primary sexual characteristics:

These are present at birth.

There is a clear difference between male and female.

Secondary sexual characteristics:

These develop during puberty under the influence of hormones.

These secondary sexual characteristics make the differences between males and females even clearer.

Asexual Reproduction in Animals

1. Some very small animals are so small they can reproduce by mitosis.
2. A hydra can reproduce by budding, many species of jellyfish reproduce this way too.
3. Some animals can reproduce by means of fragmentation. This means that they can break off a piece of themselves and a whole new organisms can grow from that piece. Flatworms, starfish and seasponges can do this.

Sexual Reproduction in Animals

Most animals that have sexual reproduction have 3 phases:

1. Pre-fertilization (the gametes also known as sex cells are produced and prepared).
2. Fertilization (the sex cells are brought together somehow and melt together to form on cell "zygote").
3. Post-Fertilization (the zygote start dividing by mitosis and becomes and embryo which continues to grow).
