| Question | Answer |
|---|---|
| What is a gametes? | Vehicles that transfer genes from one parent to the other. |
| What is a somatic cell? | a cell that contains 46 chromosomes; 23 from mom and 23 from dad |
| what is a locus? | a gene specific locations along the chromosome |
| asexual production | a single cell is the parent of the offspring. (gives rises to a clone) |
| karyotype | Chromosomes are arrange from largest to shortest and displays homologous chromosomes. |
| Sex chromosomes are... | XX- females XY males |
| All other chromosomes other then sex chromosomes are called | Autosomes |
| any cell with two chromosomes sets are called | Diploid cell (2n) |
| any cell with a single set of chromosomes are called | Haploid cell (n) |
| How many chromosomes does a somatic cell have? | 46 chromosomes |
| What are the steps of meiosis? | (PMATC) prophase metaphase anaphase telophase cytokinesis |
| What happens during prophase1? | Chromsomes condense homologs begin to physically connect (synapsis) crossing over centrosomes movement and spindle froms nuclear envelope forms microtublers are attached to the kinetochores |
| what happens during anaphase1? | Breakdown of protien cause homologs to separate homologs move towards opposite poles |
| what happens during telephase and cytokinesis? | clevage furrow division of cytoplasm nuclear envelope is form. |
