Term
Today, how do we learn about traits and their expression?
Definition
Restriction enzymes
Electrophoresis
Base pair sequencing
Term
Monohybrid cross
Definition
2 parents differ by a single trait
Term
Mendel's Law of Segregation
Definition
For each trait(gene), each organism carries two factors(alleles), and that each of the organism's gametes, or sex cells, carries only one of these factors.
Term
Law of Independent Assortment
Definition
Alleles for one trait will separate independently of the alleles for another trait. This ensures genetic variability

Carbon
Nitrogen
Biotin
Trace elements
