1 How do chromosomes determine sex and some diseases

2 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

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

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

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

Karyotype Notes. A karyotype is a “ picture ” of a person ’ s chromosomes. Each person has 46 chromosomes, in 23 pairs. Pairs 1-22 are called Autosomes.

Mistakes in Meiosis. Non-Disjunction a type of mistake in meiosis that happens to the CHROMOSOME It is the failure of homologous chromosomes to separate.
