Question

Choose which statements are true using the information presented in the phylogenetic tree below Przewalski Domestic HalfAss Wild Ass Mountain Grevy Burchell Quagga (Onager) Horses Zebras The mountain zebra is more closely related to the wild ass than to the half ass. The horses and zebras share approximately 93% of their genomic sequence. The domestic horse is more closely related to any zebra than to the wild ass. The percentage similarity between two species can be calculated by tracing the branch length. The Przewalski horse is the ancestor of the guagga zebra.

Explanation / Answer

In formation which can be extract from such phylogenetic tree is to calculate the gentic variation between two species by calculating the branch length so,

Answer 4 is right : the percentage similarty between two species can be calculated by tracing the branch length.

for example genetic similarties between mountain zebra and wild ass is 62.5 %
