**(the making of Sex cells) is a tremendous source of genetic variation.**

When sex cells come together they combine 2 half sets ( haploid ) to form a complete set ( diploid ** ) **

 * This leads to tremendous variation each generation **

 * Meiosis VS Mitosis **
 * Use the animation below to understand how Meiosis is a source of variation **

Try This! Step 1 Let’s consider how genes sort independently from each other when eggs or sperm are made. Consider 2 genes, eyesight and hair type.

S – Normal vision (dominant) s – Nearsighted (recessive)

Y – Curly hair (dominant) y – straight hair (recessive)

Jack has the following genotype, having inherited dominant and recessive genes from his parents:

Genotype: SsYy What is his phenotype for sight and hair: media type="custom" key="5895971"

Step 2  Click on the animation above. Watch and listen to the animation.

 What are the 4 different sperm combinations that could result? (Answer this in your notebook)

 In your own words explain how meiosis explains how a recessive gene can skip a generation (at least 3 sentences?)
