D3.1 Reproduction question 1
This redwood tree (Sequoia sempervirens) was blown over in 1936, but five side branches formed new roots and are now separate trees.
Three of the new trees formed from side branches of the original tree
If the genomes of the five new trees were sequenced, predict with a reason how similar they would be to each other.
