Genetics and Meiosis STARTS WITH ?
1. The mixing up of maternal and paternal chromosomes during Anaphase I is called
I __ __ __ __ __ __ __ __ __ __ A __ __ __ __ __ __ __ __ __
2.Type of cell division in which a 2n parent cell produces 4 haploid daughter cells
= M __ __ __ __ __ __.
3. C __ __ __ __ __ __ __ O __ __ __ is the exchange of DNA between homologous
chromosomes during Prophase I of meiosis.
4. Reproductive cells (sperm and eggs) are called G __ __ __ __ __ __.
5. The pairing up of homologous chromosomes during Prophase I is called
S __ __ __ __ __ __ __
6. When synapsis happens, the group of 4 chromatid arms is called a T __ __ __ __ __.
7. Independent assortment happens during A __ __ __ __ __ __ __
____ of meiosis.
8. Organisms used M __ __ __ __ __ __ for growth, repairing injuries, and replacing worn
out cells.
9. Type of cell division in which genetic recombination occurs = M __ __ __ __ __ __
10. Interphase II is different than Interphase of mitosis because the cell skips S phase and
does not copy its D __ __ in meiosis.
11. Synapsis and crossing over occur during P __ __ __ __ __ __ __ ____ of meiosis.
12. A H __ __ __ __ __ __ cell has only ONE COPY of each chromosome,
13. Type of cell division in which bacterial cells reproduce asexually
= B __ __ __ __ __ F __ __ __ __ __ __
14. The phase that is skipped or shortened in meiosis is I __ __ __ __ __ __ __ __ __ ____
15. Genetic recombination in meiosis results in daughter cells that are
D __ __ __ __ __ __ __ __ from each other and from the parent cell.
16. H __ __ __ __ __ __ __ __ __ chromosomes are the same size, shape, carry genes for
the same traits, and pair up during synapsis.
17. 2n cells are also called D __ __ __ __ __ __ cells.
18. Body cells can also be called S __ __ __ __ __ __ cells.
19. C __ __ __ __ __ __ __ O __ __ __ , S __ __ __ __ __ __ __ __ __ __, and
I __ __ __ __ __ __ __ __ __ __ A __ __ __ __ __ __ __ __ __ all result recombination
of DNA.
20. The failure of homologous chromosomes to separate during meiosis is called
_N_ __ __ __ __ __ __ __ __ __ __ __ __ __.
21. _D_ __ __ __ syndrome is also called _T_ __ __ __ __ __ __ -21 because persons with
this disorder
have three #21 chromosomes.
22. The chromosomes that DO NOT determine sex are called _A_ __ __ __ __ __ __ __ __.
23. Humans have two _S_ __ __ _C_ __ __ __ __ __ __ __ __ __ __ called X and Y.
24. A photograph of a cell’s chromosomes grouped in pairs in order of size called a
_K_ __ __ __ __ __ __ __ __ can tell a person’s sex and some chromosomal
abnormalities such as
Down or Turner’s syndrome.
