Question

Part D Apply what you have learned in the video to this new scenario focusing on four species of plants. Analyze the data matrix and phylogenetic tree to determine whether each statement is true or false A B C D E Plant 1 0 0 0 0 0 Plant 1 Plant 2 1 1 1 1 1 Plant 2 Plant 4 0 0 Plant 3 1 1 1 1 0 1 1 0 Plant 4 Plant 3 Drag "True" or "False" to the end of each statement. True Imagine if characters LG, H, I, and J were added to the data matrix, she Plants 2 and 4 but absent in Plants 1 and 3. This additional information w False

Answer 1

From the given data, we can observe that there are a total of four clades, namely, plant 1, plant 2, plant3, and plant4. Out of these, 2 and 4 appear most closely related, as they share a recent common ancestor. Presence of a trait in these plants, but absent in plant 3 will increase our confidence in the fact that plant 2 and 4 are more closely related than either is to plant 3. Similarly, the presence of traits in 2 and 4 but absent in 1 and 3, would increase our confidence in the overall tree. these traits can be either DNA or a particular protein. Also, trait E is unique to plant 2, its development stopped in plant 4.

Thus, the correct answers should be:

Imagine if characters F, G, H, I, and J were added to the data matrix, showing that they are present in Plants 2 and 4 but absent in Plants 1 and 3. This additional information would increase your confidence in the relationships shown in the phylogenetic tree. ----TRUE The phylogenetic tree shows correctly (based on the data matrix) that Plant 2 and Plant 4 are more closely related to each other than either is to Plant 3 --- TRUE The letter A could represent a morphological trait, such as the presence of flowers, or a molecular trait, such as a particular DNA nucleotide sequence -- TRUE The phylogenetic tree shows correctly (based on the data matrix) that trait E is unique to Plant 4. --- FALSE. Five taxa are included in this data matrix. --FALSE.
