The event that occurs during meiosis I is that homologous chromosomes separate.
What is meiosis?
Meiosis is a kind of cell division where a diploid cell divides into four haploid cells, which develop to produce gametes.
Meiosis is the process of gamete formation made up of two series of successive divisions namely;
Meiosis I
Meiosis II
In meiosis I, the homologous chromosomes separate into two sister chromatids. Homologous chromosomes are two similar but non-identical chromosomes formed from both parents.
Therefore, the event that occurs during meiosis I is that homologous chromosomes separate.

I believe the answer is Offspring that fail to develop. Post-fertilization barriers is where fertilization occurs but hybrid cannot reproduce. There two types of post fertilization barriers; Hybrid in-viability where the Zygote cannot complete development b/c genetic instructions are incomplete. The other one is Hybrid sterility where the hybrid organism cannot produce offspring b/c chromosome number is odd.
The answer to the question is D
Answer:
1. Molecular evidence: similar proteins and genes found in closely related species, even if those genes are not used by an organism.
2. Fossil evidence: organisms changing form over time through the fossil record.
Direct observation. We can directly observe small-scale evolution in organisms
with short lifecycles (e.g., pesticide-resistant insects).
