How many chromosomes will be found in a cell at the end of Metaphase in a normal human cell? |
|
|
|
Anaphase |
The phase of either process in which chromosomes "spilt" |
|
|
|
Incomplete dominance |
When two alleles produce an intermediate phenotype, the gene is... |
White and red flowers make pink flowers |
|
|
Antigen |
A protein that sticks out of the cell membrane and helps identify cells to the body |
|
|
|
Major differences between mitosis and meiosis |
Meiosis: haploid cells, 4 cells, n Mitosis: diploid, Metaphase 1 homologous chromosomes line up at the center, 2 cells, 2n |
|
|
|
Metaphase |
When chromosomes meet at the centerline of the cell |
|
|
|
Mitosis |
If a cell produces two new cells that have exactly the same DNA |
|
|
|
Telophase |
The phase of mitosis in which new cells form |
|
|
|
Female |
A person has XX on their 23rd chromosome |
|
|
|
Centromere |
The central part of a chromosome where spindle fibers attach |
|
|
|
Co-dominance |
A situation in which both alleles are expressed in the phenotype |
Blood type |
|
|
Multiple Alleles |
When there are more than two alleles for a particular trait |
Eye color |
|
|
Egg formation |
It goes through meiosis and an unequal division of cytoplasm leaving 3 polar bodies and an egg cell |
|
|
|
Processing Eukaryotic cells |
Promoter sequences, after RNA is transcribed intros are taken out, exons are splices together and then translated |
|
|
|
Null |
If a mutation results in a loss of function |
|
|
|
Neutral |
If a mutation does not change function of an allele |
|
|
|
Epistasis |
When the effects of one gene mask another |
|
|
|
Crossing Over |
When homologous chromosomes swap genes |
|
|
|
Di-hybrid Cross test cross |
1:1:1:1 |
|
|
|
Linkage |
When variations appear in results |
|
