Answer:When we draw a phylogenetic tree, we are representing our best hypothesis about how a set of species (or other groups) evolved from a common ancestor^1

start superscript, 1, end superscript. As we'll explore further in the article on building trees, this hypothesis is based on information we’ve collected about our set of species – things like their physical features and the DNA sequences of their genes.
Explanation:
<span>The amount of genes we have is considered an estimation. They
used to believe it was around or above 100,000. Then when the human genome project (HGP)
was completed in 2003 their estimation brought it down to 20,000 to 25,000. You
can find their current work at “national human genome research institute” and
also a free public database. </span>
E. Crossing a red flower with a white flower yields a pink flower
The hypothesis of blending inheritance states that the traits received by an organism resulting from sexual reproduction are intermediate between the traits of its parents. In this case, one parent was red and the other was white, and the offspring got the intermediate trait, which was pink.
Answer: C
Explanation: It would be C because a deletion mutation involves the loss of genetic material, therefore C is the only option that fits the definition.
Hope this helps
A young insect looks like a smaller version of an adult depending on the species. Which in incomplete metamorphosis the insect would be called a nymph for it being much smaller than the adult insect. Hope that helps!
