According to endosymbiotic theory...
- two bacterial cells merged and became a new kind of prokaryotic cell, called an Archaea
- eukaryotic cells evolved and differentiated into the two known groups of prokaryotic cells
- eukaryotic cells evolved from a symbiotic mutualism between an archaea and a bacterium

Prokaryotic cells: Domains: Archaea and Bacteria Evolutionarily older than eukaryotic cells Lack a nucleus and membrane-bound organelles Single circular chromosome with some smaller plasmids Always unicellular Eukaryotic cells: Domain: Eukarya Have a nucleus and membrane-bound organelles Pairs of linear chromosomes May be unicellular or multicellular

In fruit flies, presence or absence of wings is a Mendelian trait found on an autosome. Vestigial wings (n) are recessive to normal wings (N). In a lab, a heterozygous fly is crossed with a homozygous dominant fly. Complete the Punnett Square below and write in the probability that an offspring will be born with vestigial wings.

Flower color in snapdragons is a trait that has two alleles, one resulting in red flowers and one resulting in white flowers, and that displays incomplete dominance. Two heterozygous snapdragons are crossed. Complete the Punnett square below and label the flower colors (phenotype) associated with each offspring genotype.
