1.if two organisms are in different families, they must be in different phyla. true or false
2.if two organisms are classified in the same genus, what must also be true?

Q1. The answer is False.

There are eight main taxonomic groups: domain, kingdom, phylum, class, order, family, genus and species, with the domain as the most inclusive and species as the least inclusive. Hence, one phylum will include many families. This means that two organisms from different families may be in same phyla.


Q2. The answer is they must have the same family, order, class, phylum, kingdom, and domain.

Main taxonomic groups from the most inclusive to the least inclusive are: domain
kingdom
phylum
class
order
family
genus
species

Thus, if two organisms are in the same genus, they must have the same family, order, class, phylum, kingdom, and domain.
