I am working on human chromosomal speciation but cannot confirm how a "head to head telomeric fusion" (not a Robertsonian translocation) such as human chromosome 2 would express itself in the first generations. About 2/3 down there is a paper with a Punnett square of the event ...

But it does not talk about offspring, as one of the symptoms is infertility as an adult, thus ...
