question 8 of 20
which statement about the figure is false?
centric fusion between chromosomes 2 and 3 does not disrupt chromosome pairing.
centric fusion between chromosomes 1 and 2 and chromosomes 2 and 3 becomes fixed.
centric fusion between chromosomes 1 and 2 disrupts chromosome pairing during meiosis.
normal pairing of chromosomes cannot occur in hybrids.
the ancestral population separates into two independent lineages.

Explanation:

Centric fusion between chromosomes 2 and 3 does not disrupt chromosome pairing as shown in the figure. Centric fusion between 1 and 2 does disrupt pairing during meiosis. Normal chromosome - pairing can be affected in hybrids, and the ancestral population can split into lineages. Centric fusion events can become fixed over time.

Answer:

Centric fusion between chromosomes 2 and 3 does not disrupt chromosome pairing. This statement is true based on the figure.
Centric fusion between chromosomes 1 and 2 and chromosomes 2 and 3 becoming fixed is a possible long - term outcome and is not false from the information given.
Centric fusion between chromosomes 1 and 2 disrupting chromosome pairing during meiosis is consistent with what is shown.
Normal pairing of chromosomes cannot occur in hybrids is a valid statement in the context of chromosomal rearrangements.
The ancestral population separating into two independent lineages is also a valid scenario. So, the false statement is not among the given options as all seem to be consistent with chromosomal fusion and speciation concepts. If we assume there is an error in the question setup and we have to pick one, we note that "Centric fusion between chromosomes 2 and 3 does not disrupt chromosome pairing" is the most directly observable and least likely to be false based on the figure. So, if forced to choose, the answer would be:
Centric fusion between chromosomes 1 and 2 and chromosomes 2 and 3 becomes fixed. (This is chosen as it is the least supported by direct visual evidence in the figure compared to the others which have more clear - cut visual or conceptual support).
