If two organisms are able to carry out the same life function, we can expect to find which of the following?
a
both organisms have specialized cells for this function.

b
this function evolved in the two organisms at the same time.

c
both organisms live in the same habitat.

d
these organisms have an identical number of chromosomes.

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.
