|
|
What is chromatin
|
the generic term for any complex of DNA and protein found in a cells nucleus

Histocompatibibily Antigens
|
carried by all bodies cells except red blood cells and sperm they play a crucial role in stimulating proper immune response that destroys intruders while keeping the bodies own tissues intact

|
|
Lethal Allele
|
a mutated allele that falls to code for the production of a functional protein that is vital for life dominant lethal allele quickly eliminated from the population recessive lethal allele will only cause death in homozygous recessive condition carrier is an individual who is heterozygous for the lethal allele
