Study Notes
- A diploid cell contains two of each kind of chromosome.
- A haploid cell contains one of each kind of chromosome.
- Gametes are sperm or egg cells.
- Homologous chromosomes have the same genes for the same traits in the same order.
- Parent cells create gametes through meiosis.
- Crossing over is the exchange of genes by non-sister chromatids.
- A zygote is created when a sperm fertilizes an egg.
- Somatic cells, also known as body cells, include all cells besides sperm and egg cells.
- Fertilization is the process of a sperm cell joining with an egg cell.
- Humans have 46 diploid chromosomes.
- Humans have 23 haploid chromosomes.
- Egg and sperm cells are considered haploid.
- Somatic cells are considered diploid.
- The chromosome number is not related to the complexity of an organism.
- Crossing over occurs during prophase in meiosis.
- Two daughter cells are created at the end of meiosis 1.
- Four daughter cells are created at the end of meiosis 2, and these are considered haploid.
- In humans, each cell contains 46 chromosomes at the end of meiosis 1.
- The important outcome of meiosis 1 is crossing over.
- The important outcome of meiosis 2 is four haploid cells.
- Meiosis results in genetic variation and produces four haploid daughter cells, and it consists of two sets of division.
- Meiosis provides genetic variation through crossing over and fertilization.
