Two populations that inhabit the same area but remain genetically distinct can best be called:
A
inbred lines
B
hybrid populations
C
allopatric species
D
sympatric species
Verified step by step guidance1
Step 1: Understand the key terms related to population genetics and speciation. 'Inbred lines' refer to populations bred to be genetically uniform, often through controlled breeding.
Step 2: Recognize that 'hybrid populations' are groups formed by the interbreeding of two distinct populations, resulting in mixed genetic traits.
Step 3: Know that 'allopatric species' are species that live in separate geographic areas, preventing gene flow between them.
Step 4: Define 'sympatric species' as species or populations that live in the same geographic area but remain genetically distinct due to reproductive isolation mechanisms.
Step 5: Conclude that since the problem describes two populations inhabiting the same area but remaining genetically distinct, the best term to describe them is 'sympatric species'.
