You have learned that humans have a total of 46 chromosomes and that chimpanzees have a total of 48 chromosomes. Use other textbooks in biological anthropology and biology (or reputable online resources) to find the number of chromosomes in other organisms. Give an organism with considerably more chromosomes than humans. Give an organism with considerably fewer chromosomes than humans. Did your findings surprise you? What did your research suggest about the relationship between chromosome number and organism complexity?

Answer 1

Answer:

The correct answer is included in the Explanation section

Explanation:

An organism with considerable more chromosomes than humans: the plant Ophioglossum reticulatum with 1260 chromosomes.

An organism with considerable fewer chromosomes than humans: the ant Myrmecia pilosula with 1 chromosome.

It might be thought that the chromosome number of a species is directly related to its complexity, meaning that an organism with a large number of chromosomes is more complex than an organism with a small number. However, this is not true. Chromosomes are structures of coiled DNA, and its number indicate how the cells wrapp their genomic material when they reproduce. The number of chromosomes is not related to the organism complexity, but rather the number of genes and their function.

A king and his army will attempt to capture a fortress. The left and right flanks break off from the main group to attack the west and east guard towers. Suppose the left flank has a 60% chance of success and the right flank has a 75% chance of success, independently of one another. If both flanks capture their respective targets, then the king has a 98% chance of successfully taking the fort.
