Meiosis Vocabulary and Notes
What looks similar between mitosis and meiosis? What looks different? Prophase Interphase Mitosis Cytokinesis Telophase Metaphase Anaphase Meiosis
Vocabulary- Meiosis Process of reduction division in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell.
Vocabulary- Homologous a pair of chromosomes, one from each parent, which carry genes for the same traits.
Vocabulary- Diploid term used to refer to a cell that contains both sets of homologous chromosomes.
Vocabulary- Haploid term used to refer to a cell that contains only a single set of genes.
Check for Understanding A diploid cell has __________ number of chromosomes.
Check for Understanding A haploid cell has __________ number of chromosomes.
Vocabulary- Crossing Over process in which homologous chromosomes exchange portions of their chromatins during meiosis.
