1. In the early 1900s, scientists noted that chromo- genotype; phenotype
some movements during cell division in reproductive
cells mirrored the patterns of inheritance described
by Mendel. These results and others confirmed that
Mendel's hereditary units (genes) were located on chro-
mosomes. The sum total of chromosomes in an organ-
ism constitute its __________, whereas the organism's
observable traits constitute its __________.
2. Which domain(s) of life include(s) multicellular organ- Eukarya
isms?
3. Watson and Crick derived their model of DNA struc- Percentages of adenine
ture not from their own laboratory research but rather and thymine are approx-
