1. You can describe what the genotype and phenotype are. 
2. You can explain that cells only use the hereditary information that they need. 
3. You can explain how each of the parents supplies 50% of the chromosomes. 
4. You can say how the sex of humans is determined by sex chromosomes. 
5. You can explain how sexual reproduction causes variation in genotypes.
