How does the theory of punctuated equilibrium explain the gaps in the fossil
records?
A) Bursts of rapid evolution in a species is unlikely to be found in fossil records.
O
B) Fossil records of organisms that evolve due to mutation are difficult to find.
C) It's unlikely that all evolutionary stages of an organism are preserved.

During crossing-over, a. genetic material is exchanged between nonsister chromatids, resulting in new combinations of alleles. b. nonsister chromatids from each homologous chromosome of a tetrad are exchanged, resulting in new combinations of alleles. c. one homologous chromosome of a tetrad is exchanged with another tetrad, resulting in new combinations of alleles. d. sister chromatids from each homologous chromosome of a tetrad are exchanged, resulting in new combinations of alleles. e. genetic material is exchanged between sister chromatids, resulting in new combinations of alleles.
