The figure which follows the three steps needed for the occurrence of
Introduction:
A biological species can be defined as a group of individuals that can breed together but cannot breed with any other group. The group shows reproductive isolation from other groups. The biological species concept states that a species essentially or potentially interbreed in nature but not on the basis of similarity in appearance.

Using the information from the DNA-DNA hybridization data table below, build a phylogenetic tree that shows the relationship between species E,R,P,G, and U. Create a scale on the side before you draw it
D) Two dragonfly populations that have accumulated several differences in their DNA sequences
How do you know that is the answer? I thought we were not allowed to use DNA sequences in the lineage species concept.
Can you answer all the parts to this diagram
Species 1 and 2 are sister species from which you’ve cloned related genes. On the gene tree on the top of the next page, use labels to answer the following questions:
(a) Label the node that represents a gene duplication with “D,”
(b) Label the nodes that represent speciation events with “S,”
(c) Pick a pair of genes that are paralogs and label them both “P.”
(d) Pick a pair of genes that are orthologs and label them both “O.”
