Question
Answer
genetics   the scientific study of heredity  
🗑
dominant gene   the strong gene, if it is present whatever it is representing will show  
🗑
hybrid   two different genes for a given trait  
🗑
genotype   gene combination for a given trait  
🗑
phenotype   outward appearance of the genotype  
🗑
girls can only hold...   x chromosomes  
🗑
boys can hold both...   y and x chromosomes  
🗑
sex linked trait   traits that are carried on the x chromosomes of the 23 par of the double helix  
🗑
sex linked traits cannot be on the...   y chromosome  
🗑
incomplete dominance   AKA co dominance; the situation where more than one gene is dominant for a given trait  
🗑
in incomplete dominance...   one gene cannot over power the other  
🗑
traits are passed from...   parent to offspring  
🗑
gene traits determine...   traits  
🗑
genes will always be inherited...   in pairs  
🗑
genes are either...   dominant or ressessive  
🗑
meiosis   cell division of gametes resulting in half the # of chromosomes  
🗑
DNA   deroxyribo nucleic acid  
🗑
double helix   the twisted ladder structure that human DNA takes  
🗑
a only pairs with...   t  
🗑
c only pairs with   g  
🗑
mutation   mistake in DNA  
🗑
mutigan   anything that causes a mutation  
🗑
internal mutation   caused when the pairs are replicated wrong  
🗑
inherited disease   passed to the offspring genetically ex. hemophilia  
🗑
selective breeding   pick the traits that you like from the parent generation and breed  
🗑
gene transfer   moving a single gene from one organism to another  
🗑
why gene transfer bacteria?   reproduce quickly, easy to work with, inexpensive  
🗑
splice   using enzymes to remove a gene from a chromosome  
🗑
recombinant DNA   mixing DNA from different sources to create an entirely new organism  
🗑
cloning   the creation of an organism that is an exact genetic copy of an other  
🗑
SCNT   somatic cell nuclear transfer  
🗑
somatic cell nuclear transfer   in SCNT there is no mixing in DNA  
🗑
mRNA   messenger RNA; carries message as to what protein is needed  
🗑
tRNA   transfer RNA; arranges the protein chain to create what was ordered by mRNA  
🗑
karyotype   gene map done by a genetisist that can tell if there disorder or gender  
🗑
cell   the basic unit of life  
🗑
cell --> tissue --> organs --> ___ --> ___   systems --> organism  
🗑
Robert Hooke   coined the word "cell". Also the first person to view cells under a microscope  
🗑
vonLeewonhock   first to view animal cells under a microscope  
🗑
spontaneous generation   mistaken belief that life can arise from a nonliving source  
🗑
Louis Pastur   demonstrated that new bacteria grew only with existing bacteria  
🗑
cell theory1   all living things have cells  
🗑
cell theory2   cells are the basic unit of function and structure in a living thing  
🗑
cell theory3   cells can only come from other living cells  
🗑
reproduction    
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
