- egg donor & sperm donor
gene :
region of ONA

hair color gene could be diff , but in same location
allele :
different versions of gene

physical trait
most physical traits made up of so genes
asexual reproduction
- identical (genetically/ offspring
~ 100 % reproduction success
~ conserves energy
~
don't need mate

no diversity+ not robust to changes/viruses

gap)
-
some plants/fungi can do both (sexual & asexual
cell cycle -
cell lifetime
cell division-mitosis ,
asexual reproduction
~ mitosis :
make sure two cells have ONA
~
Cytokinesis :
Split cytoplasm fuck cancer
Cancer : One cell loses control of reproduction 1) growth 2) invasion 3) metastasis
~
forms tumor
~
more cells ,
more mutations
- metastasize :
cancer moves to other parts of body
benigh tumors remain at original site
Malignant tumors spread
Cancer treatments
~ surgical removal
- chemotherapy
~ limit spread but attack normal cells
-
immunotherapy
