DNA: The Inherited Material Responsible for Variation
DNA -Transmitter of Genetic Code
chromosome
packager of DNA
DNA
the instructions of life
spiral, ladder shape
G C A T
guanine, adenine, cytosine, thymine
genetic code
the instructions given based off of the arrangement of G, C, A, T
alleles
all the possible gene combinations
gene
uninterrupted segments of DNA that give specific instructions
Cell Division
Meiosis
sex cells
two cell divisions
Mitosis
body cells
DNA replication
is important because without it the daughter cells would be incomplete
Patterns of Inheritance
dominant trait
trait that shows up regardless
recessive trait
a trait that shows up
only
when paired with another recessive trait
purebred
something that's ancestors all shared the same traits
hybrid
when two
different
purebreds have offspring
incomplete dominance
when two non-dominant, non-recessive traits blend
when a red flower and a white flower produce a pink flower
