Cell Aggregation & Differentiation is common to all Dictyostelids.

It consists of an interconnected programme of cell movement and cell differentiation.

Recombination is also reduced within a pericentric inversion. No dicentric bridges or acentric fragments are produced.

#Unit 8. Inheritance Biology

Recombinant chromosomes have too many copies of some genes and no copies of others, so gametes that receive the recombinant chromosomes cannot produce viable progeny.
