Presentation transcript:

How do chromosomes determine sex and some diseases

Learning Objectives State where our genetic information is found Interpret the information shown in karyotypes Describe the result of an extra chromosome 21 Show how our sex (boy or girl) is inherited

Karyotype (male) State the total number of chromosomes in each cell Identify the sex chromosomes

Karyotype (female) State the total number of chromosomes in each cell Identify the sex chromosomes

Inheritance of sex Copy the diagram Explain why it is the sperm that determines the sex of a baby
