supplementary
complementary
recessive
Sex is determined by a pair of sex chromosome called:
Autosomes
Chromosomes
Sex-linked genes
All of these
Because most of the amino acids are represented by more than one codon, the genetic code is

An organism with two identical alleles is
dominant
hybrid
heterozygous
homozygous
Nucleotide arrangement in DNA can be seen by
X-ray crystallography
electron microscope
ultracentrifuge
light microscope
