Answer:
The results indicate that two independently assorting genes are involved (modified 9:3:3:1 ratio), with white blocking the expression of color by the other gene. The ratio of white : color pups is 3:1, indicating that the F.1 is heterogeneous (W/w). Among colored dogs, the ratio is 3 black : 1 brown, indicating that black is dominant to brown, and the F.1 is heterogeneous (B/b). The original brown dog is w/w ; b/b, and the original white dog is W/W ; B/B. The F.1 progeny are W/w ; B/b, and the F.2 progeny are: 12: 3: 1.

Becuase they were fully aquatic unlike tetrapods today
Answer:
Explanation:
Biodiversity varies with a change in altitude or latitude. The diversity increases as we move from high to low altitudes (i.e., from poles to equator). ... There is a decrease in species diversity from lower to higher altitudes on a mountain.
The set of species derived from one common ancestor.
To build phylogenetic trees, a variety of data can be employed, including genetic information, mitochondrial DNA sequences, ribosomal RNA genes, and any relevant genes, as well as morphological information such as structural characteristics, organ kinds, and specific skeletal arrangements
<h3>What is a Phylogenetic tree ?</h3>
A phylogenetic tree, also called a phylogeny, is a diagram that shows the evolutionary branches from which various species, creatures, or genes have descended from one another.
- A phylogenetic tree can be used to track a species' evolutionary history back via the tree's branches and find their common ancestors along the way.
- A lineage may preserve some of its ancestors' characteristics over time, but it will also change over time to accommodate the environment.
