Study Guide by Me ;]
| Question | Answer |
|---|---|
| What is a Somatic Cell? | Body Cells |
| What is a Gamete? | Sex Cells |
| Are Somatic Cells Haploid or Diploid? | Diploid |
| Are Gamete Cells Haploid or Diploid? | Haploid |
| Name an example of a Somatic Cell: | Blood cells, Skin cells, Lung cells, ect. ect. |
| Name an example of a Gamete Cell: | Eggs 'n Sperm |
| What are Diploid Cells? | Cells with 2 full sets of chromosomes (2n) |
| What are Haploid Cells? | Cells with 1 full set of Chromosomes (n) |
| How many Chromosomes do Diploid Cells have? | 2n = 46 |
| How many Chromosomes do Haploid Cells have? | n = 23 |
| What are Autosomes? | Chromosomes that carry traits |
| What are Sex Chromosomes? | Ditto but they determine your sex |
| What is a Karyotype? | A Diagram that show the number and appearance of the chromosomes in a cell |
| What is Meiosis? | The process of cell division that makes gametes in the gonads |
| What is a Gonad? | Ovaries(Female) and Testes(Male) |
| What is Sexual Reproduction? | When to parents fuse their gametes together to create an offspring that has both of their genes |
| What is Fertilization? | fusion of egg and sperm to form a zygote |
| What are Homologous Chromosomes? | Chromosome pairs that have the same types of genes |
| What are Sister Chromatids? | 2 Identical copies of the same chromosome |
| What is Meiosis I? | Separation of Homologous Chromosomes |
| What is Meiosis II? | Separation of Sister Chromatids |
| What is crossing over? And what is its significance? | When chromosomes exchange genes; Creates new combos of genes |
| What can happen if there is a mistake during Meiosis? | Genetic Disorders |
| What can happen if there is a mistake during Mitosis? | Genetic Disorders |
| What is the result of Meiosis? | 4 Haploid daughter cells |
| What is the result of Mitosis? | 2 Diploid daughter cells |
| Be able to draw the phases of Meiosis/Mitosis, as well as be able to label the steps. (flip 2 c more) | Be able to tell a Haploid cell from a Diploid cell. |
