GENETIC ENGINEERING  
techniques and procedures used in gene manipulation
GENETIC ENGINEERING  
often referred to as GMO
CLASSICAL BREEDING  
focuses on mating of organisms
interbreeding
TARGET DNA  
the gene of interest
codes for the desired trait
RESTRICTION ENZYMES  
These enzymes identify specific base sequence and cut theDNAa at a specific point between two nucleotides
DNA CLONING VECTORS  
used to carry the target DNA to be transferred into the host DNA
HOST CELL  
accept the target DNA to multiply or replicate it
MODIFYING ENZYME  
enzymes involved in degradation,synthesis,alteration of the nucleic acids
GENE  
sequence of DNA that codes for a specific trait
ALLELE 
alternative forms of genes
LOCUS  
location of the genes in the chromosomes
DOMINANT  
allele that is EXPRESSED
represented by UPPERCASE LETTERS
it is the trait that will be appearing
RECESSIVE  
allele that is NOT EXPRESSED
represented by lowercase letters
HETEROZYGOTE  
combination of different alleles
GENOTYPE  
combination of genes represented
PHENOTYPE  
the appearance of the specified genotype
TEST CROSS  
use to determine if an individual with dominant trait
PARENTAL GENERATION  
first genotypes that are crossed
GREGOR MENDEL  
father of genetics
LAW OF SEGREGATION  
alleles coming from the parents combine during fertilization
LAW OF INDEPENDENT ASSORTMENT  
separate genes for separate traits are passed independently of one another
LAW OF DOMINANCE  
when parents with pure,contrasting traits are crossed together,only one form of trait appears in the next generation
INCOMPLETE DOMINANCE  
the heterozygote is intermediate in appearance between the two homozygotes .Neither allele is completely dominant over the other allele
CODOMINANCE  
the heterozygote shows some aspect of the phenotype of both homozygote
can be distinguished from incomplete dominance by the appearance
MULTIPLE ALLELES  
a gene may have three or more allele
more than two alleles for a trait exist in a population
