All organisms composed of basic units called cells. Each sperm thought to contain a mini adult. Natural selection: populations consist of more individuals that can be supported by resources. 1856-1863, published 1866 determined that flower color and other traits were controlled by genes that occur as pairs. Karyotype: a set of chromosomes within a eukaryotic cell. A stretch of dna that codes for a protein or rna chain that has some function. 1950s double helix made up of 2 complementary strands of nucleotides. ***read about dna vs proteins as mode of inheritance*** 1910 white eye fly: mutant red eye flies: wild type.
