meiosis star review
| Question | Answer |
|---|---|
| Meoisis | the cell division process that produces sex cells, 4 genetically identical diploid cells |
| Mitosis | the cell division process that produces body cells, 2 genetically identical diploid cells |
| Sexual reproduction | producing offspring that are genetically different than the parents |
| asexual reprouduction | producing offspring that are genetically the same as the parent |
| nondisjunction | an error in meoisis where the chromosomes don't split evenly, can cause downs, timer, or klinifelter |
| gamete | sex cell (sperm or egg) that is haploid or half of the usual number of chromosomes |
| crossing over | during meiosis 1, homologous chromosomes parts will switch with each other. generating genetically different gametes |
| independent assortment | the random lining up of homologous chromosomes in the middle of a cell during meiosis 1 |
| incomplete dominance | neither allele is completely dominant, leading to blended intermediate phenotype |
| Codominance | when both alleles appear seperately |
| Heterozygous | Aa |
