Question
Chapter 24, Problem 15A
Summary Introduction
Introduction:
A tree diagram which shows evolutionary links among different species is termed as an Evolutionary Tree. This reflects the way of how the species have evolved from a series of common ancestors
Expert Solution & Answer
Answer to Problem 15A
Correct answer:
The correct answer is option (A) an earthworm and a snail.
Explanation of Solution
Explanation/justification for the correct answer:
Option ( A) an earthworm and a snail.
According to the evolutionary tree,an earthworm is closely related to snail because an earthworm belongs to phylum Annelida and Snail belongs to phylum mollusks.. So, this answer is correct.
Explanation for incorrect answer:
Option (B) a flatworm and an earthworm
According to the evolutionary tree, a flatworm belongs to phylum
Option (C) a roundworm and an earthworm
According to the evolutionary tree, a roundworm belongs to phylum Nematoda an earthworm belongs to phylum Annelida. So, this is an incorrect answer.
Option (D) an earthworm and sea star.
According to the evolutionary tree, an earthworm belongs to phylum Annelida and Sea star belong to phylum Echinoderm. So, this is an incorrect answer.
Conclusion
According to the evolutionary tree,an earthworm is closely related to snail. Hence, the correct answer is option (A) genes.

Your edited obligate apomict plants retains all the CRISPR "machinery" necessary to convert the "sexually reproducing" allele to the "obligate apomict" allele. You plant 100 hectares of your edited obligate apomicts in order to increase seed for sale the following year. Neighboring farms and seed producers are growing many different un-edited sexually reproducing varieties of the crop. If your neighbors plant seed harvested from their crops that was pollinated by your crop, should they expect these seeds to generate apomictic or non-apomictic plants?
