6.1 Chromosomes and Meiosis
• Human body cells have 23 pairs of chromosomes and 46 total
– Each pair of chromosomes is called Homologous pairs and have copies of the same genes
– In each pair, one chromosome comes from each parent.
*Homo= same

6.1 Chromosomes and Meiosis • You have two types of specialized cells:
Somatic cells Germ cells
• Undergo mitosis
• body cells
• Diploid
• 46 chromosomes
• Identical to parent cell
• Undergo meiosis
• Cells in reproductive organs (ovaries/testies)
• Become gametes (sperm/eggs)
• Haploid
• 23 chromosomes
• Each are Unique

6.1 Chromosomes and Meiosis
Points to Ponder
1.Where are germ cells located in the human body (2 places)
2.Do you think that Y chromosomes contain genes that are critical for an organism’s survival? Explain.

6.1 Chromosomes and Meiosis
Points to Ponder
1. Where are germ cells located in the human body (2 places)
• In the reproductive organs: The ovaries in women and the testes in men.
2. Do you think that Y chromosomes contain genes that are critical for an organism’s survival? Explain.
• No, a Y chromosome is not necessary for survival. Females do not have a Y chromosome, and they are able to survive.

6.1 Chromosomes and Meiosis
• Meiosis= makes haploid cells (23) from diploid germ cells (46).
– produces gametes (sperm/eggs)– Produces genetically unique cells– Takes place only at certain times in an organism’s
life cycle– Involved in sexual reproduction– Germ cells

6.1 Chromosomes and Meiosis
1. King crab; fruit fly2. No. A porpoise is much bigger than a king crab, and has far less
chromosomes. A potato is only 3 chromosomes off from human, and far smaller.
3. Yes. Chromosomes need to be able to fit in the nucleus.
