Chromosomes align in middle of the cell: prophase 1 is where crossing over happens. What is a mendelian trait? (trait controlled by one specific allele) Why is he important? (geologic processes in the past occur now) Some homologous characters are more informative: primitive traits- traits passed on unchanged from an ancestor, derived traits- traits that develop in a particular taxon after they split from their common ancestor xiii. Evolutionary systematics: phylogram/phylogenetic trees are statements of evolutionary relationships (show branch order and branch lengths, time xiv.
